RPE is simply a measure of how hard you feel you're working. Not how fast you're going. Not what your heart rate says. How hard it feels, right now, in your legs, your lungs, and your mind. It sounds almost too simple to be useful, but there's decades of exercise science behind it, and coaches at every level of the sport rely on it daily.

Where it came from

The concept was developed in the 1960s by Swedish psychologist Gunnar Borg. His original scale runs from 6 to 20, which looks strange until you understand the logic: multiply any number by 10 and you get an approximate heart rate. An RPE of 12 corresponds to roughly 120 beats per minute. An RPE of 17 to around 170. It was a neat way to link subjective effort to objective physiology, and it's still used in clinical and research settings today.

For most athletes, the modified 1 to 10 scale is more intuitive. A 1 is barely moving. A 3 is comfortable, conversational, something you could sustain all day. A 5 is moderate, breathing noticeable but controlled. A 7 is hard, talking possible but uncomfortable. A 9 is close to your limit, unsustainable for more than a few minutes. A 10 is everything you have, and reaching it is rarer than most people think. Most training sits between 2 and 8, with true maximal efforts reserved for specific sessions. For the full breakdown, download the Boundary Cycle Coach RPE scale guide.

Why RPE matters

The case for RPE isn't that it's better than power or heart rate. It's that it measures something those tools can't: how your body is actually responding today.

Power meters show output. Heart rate shows cardiac response. Neither tells you whether you're recovered, running low on glycogen, or quietly fighting off a cold. RPE does, because it integrates all of those variables automatically. A 200-watt effort might feel like a 5 on a good day and a 7 on a bad one. That gap is information worth paying attention to.

For ultra-distance riders, this matters more than most people appreciate. On my first day of Trans Atlantic Way, I was riding at what I'd estimate was an RPE of 5. It felt manageable. I felt fresh, the road was good, and I wasn't paying close enough attention to the signals my body was already sending. By the end of that day I was suffering with nausea and spent the following day recovering before I could settle back into a rhythm at a 3 to 4. One day lost, and an uncomfortable lesson about what getting day one wrong actually costs.

That experience shapes how I think about pacing now, and how I coach it. The riders who finish strong over 300 kilometres or more are almost never the ones who went hardest early. They're the ones who held something back when everything felt fine.

Why coaches use it

Power files and heart rate data tell a coach what happened during a session. RPE tells them what the athlete experienced. Those two things are often quite different, and the gap between them is where a lot of the most useful coaching information lives.

When an athlete reports that a zone 2 ride felt like a 6, that's a signal. It might mean fatigue from the previous week hasn't cleared. It might mean life stress is bleeding into training. It might mean the zones need revisiting. A number on a screen won't surface any of that. An honest RPE score often will.

The same applies in the other direction. An athlete who records a strong power output but rates the effort at a 9 may be closer to their limit than the data suggests. That's not a rider to push harder the following week. Catching that early can be the difference between a training block that builds fitness and one that tips into overreaching.

RPE is also particularly valuable during fitness testing. When an athlete knows they're riding to a target wattage or heart rate, they unconsciously pace to that number rather than their actual capacity. That ceiling limits the test. RPE-led testing removes it, and often produces truer maximal efforts as a result.

For older athletes, heart rate becomes progressively less reliable as a training guide. Maximum heart rate declines with age, and common medications such as beta blockers directly suppress cardiac response, making HR zones inaccurate or meaningless. RPE sidesteps all of that. It doesn't care what your maximum heart rate is supposed to be. It measures how hard the effort actually feels, which remains a valid and useful signal at any age.

It also builds a common language between coach and athlete. Rather than spending time decoding data, we can have a direct conversation about how training is actually going. Over time, tracking RPE alongside objective metrics gives a much clearer picture of how an athlete responds to load, where they struggle, and when they're ready to be pushed. It's one of the simplest and most revealing questions a coach can ask: how hard did that actually feel?

When to use it

When your data disappears. Your computer dies, your power meter drops signal, or you simply don't have the equipment. RPE means you can still train with intent.

When data is misleading. Heart rate drifts upward in hot or humid conditions independently of actual effort, and responds slowly during short intervals. Using RPE alongside it helps you interpret what you're seeing rather than reacting to a lagging or inflated number. The same applies at altitude, where HR spikes disproportionately in ways that make zone-based training unreliable. RPE self-corrects for all of it automatically.

When you're returning from illness. Prescribed power and heart rate targets predate whatever you've just been through. RPE is a safer guide during the rebuilding phase, letting your body dictate the pace rather than a number set when you were fit and healthy.

When you're calibrating new training zones. An effort at threshold should feel like a 7 to 8: hard, sustainable for around an hour, but not comfortable. If it feels like a 5, your zones may be set too low. RPE is a useful sanity check that most riders skip.

During long events, and especially on hilly courses. One of the most common ways ultra rides unravel is through terrain-driven pacing. A climb appears, the rider responds to it, and without realising they've pushed well above threshold for two or three minutes. Do that repeatedly across a long day and the cumulative cost is significant. RPE helps because it anchors effort to how you feel rather than what the road is doing. The goal is to ride the pace, not the terrain. A climb should feel the same as the flat that preceded it. If it doesn't, you're going too hard.

Getting better at it

RPE is a skill, and most riders aren't naturally good at it. The tendency is to underestimate effort early in a ride and overestimate it when tired. Both improve with deliberate practice.

The simplest approach: check in regularly. Every 20 to 30 minutes, note your RPE and cross-reference it with your power or heart rate. Over time the correlation sharpens. You start to recognise what a 6 feels like in your chest, your legs, your breathing. That embodied knowledge carries across different bikes, different conditions, and different points in the season in a way that a number on a screen never quite does.

If you follow structured training plans, RPE descriptors are usually included alongside power and heart rate targets. Don't skip them. An endurance ride at zone 2 should feel easy, almost frustratingly slow. If it feels harder than that, RPE is often the first indicator that something is off, long before your metrics confirm it.

Used alongside your data, RPE makes you a more complete athlete. Used on its own when the data isn't available, it keeps your training purposeful. Either way, it's a tool worth developing. And unlike a power meter, you'll never leave it at home.

If any of this resonates, and you're wondering whether your training is as well-structured as it could be, it might be worth having a conversation. Understanding RPE is one piece of a much larger picture, and getting that picture right is exactly what coaching is for. Get in touch and we can talk through where you are and what you're trying to achieve.

Most cyclists treat winter as something to survive. Get through December to February without losing too much fitness, then rebuild in spring. I used to think the same way, grinding through endless base miles in the Kent rain. That's backwards.

This is especially true if you're training for ultra-distance events. Riders planning a 300km audax in July or a multi-day tour in August often panic about winter volume. They think they need those long base miles now or they'll never be ready. The research suggests otherwise.

Winter isn't a holding pattern. It's an opportunity to train in ways that simply don't work in summer. The cold acts as a physiological stimulus. Shorter days force you into time-efficient training blocks. And while other riders are doing slow miles in poor conditions, you can be doing the work that actually maintains your top-end fitness.

The research backs this up. More importantly, it works in practice for riders targeting everything from century rides, L'Etape du Tour or  Paris-Brest-Paris. Here's what you need to know.

Keep Your Muscles Warm (This Isn't About Comfort)

What to wear

Below 15°C, you need thermal bibs. Not summer bibs with leg warmers. Proper thermal bibs with a fleece lining. Below 10°C, add knee warmers over the top. Yes, over thermal bibs. The knee joint haemorrhages heat. Below 5°C, you want overshoes as well. Numb toes aren't just uncomfortable, they're a sign you've lost power output.

One more thing. Overdress your legs, underdress your torso. Your core generates heat. Your legs don't, not enough anyway. This took me a while to learn properly. In British winter, where the damp cold finds every gap in your kit, getting the layering right makes the difference between a quality session and just suffering.

Why this matters

Stephen Cheung's lab at Brock University found something remarkable. When your skin gets cold, even if your core temperature stays normal, your time to exhaustion drops by 31%. Not a few per cent. Thirty-one. The mechanism is straightforward. Cold skin slows nerve conduction velocity. Your brain limits how many muscle fibres it recruits because it's trying to conserve heat. You're not weak. You're mechanically limited.

Keep your muscles at operating temperature and you keep your power output. It's that simple.

Common mistakes

The biggest one? Comparing your winter watts to summer numbers. Riders panic when they see lower power numbers in January and assume they're losing fitness. Stop it. You're fighting increased air density in cold weather, which creates more aerodynamic drag. Add road resistance and usually a headwind, and your normalised power tells you nothing about fitness in January.

A better measure? Look at your power-to-heart-rate ratio. If that's stable across the season, your fitness is fine. The lower absolute numbers are environmental, not physiological.

Second mistake: thinking you'll warm up once you're going. You won't. Not properly. If you leave the house underdressed, you'll be underdressed for the entire ride. Third: numb extremities. If you can't feel your toes or fingers, you've already gone too far. Turn around.

Train in Blocks, Not Lines

The protocol

Here's what actually works when you've only got six to eight hours a week. Week one: four or five hard sessions. Intervals, tempo, threshold work. Doesn't matter hugely which, as long as it's quality. Weeks two and three: one hard session per week. The rest is easy or recovery. Properly easy, not "I'm just going to push this climb" easy. Then repeat the three-week cycle.

That's it. No complicated periodisation charts. No spreadsheets. Just three weeks of very different training stress.

Why this works

Bent Rønnestad's research group in Norway tested this exact protocol against traditional training. Same total volume. Same total intensity. Just organised differently. The block periodisation group improved VO₂max by 4.6%. Power output at lactate threshold went up 10%. The traditional group, spreading their intensity evenly across the month, saw no significant changes at all.

The theory is something called cumulative fatigue and delayed adaptation. You hammer yourself for one week, which creates a significant training stress. Then you back right off, which allows the adaptation to express itself. The traditional approach never creates enough stress to force adaptation, but also never allows enough recovery to realise it.

Winter makes this practical. You can do your hard week when conditions are good. Then when the weather turns awful, you're in your recovery weeks anyway.

What this means for ultra-distance training

This is where riders planning long summer events often get it wrong. If you're targeting a 300km audax in July, a LEL in August, or any multi-day tour, you're probably panicking about winter volume right now. You think you need to be doing 15-20 hour weeks in December to build the base for summer.

You don't. What you need in winter is to maintain your ability to produce steady power. That's intensity work, not volume. If you're only riding six hours a week through winter using block periodisation, you'll produce superior adaptations compared to grinding out twice that volume in poor conditions. The fitness you're building now is the foundation for the volume you'll add in spring.

Quality beats quantity. Always has, but especially when conditions limit your training time. For ultra-distance events, winter is about maintaining your ceiling and your steady-state power. The long rides come later, when you've got daylight and better conditions. Riders doing 15 hours of slow winter miles are getting some fitness benefit, but far less return per hour invested. More importantly, they're often arriving at spring tired rather than ready to build.

The volume will come. But it comes more productively when you've maintained your ability to ride at a decent intensity. That's what block periodisation preserves through winter.

Never Train Through Shivering

The hard rule

When you start shivering, the session is over. Add a layer if you've got one. Otherwise, go home. Not in five minutes. Now. If you get indoors and you're still shivering after five minutes, you stayed out too long. Learn from that.

I used to ignore this. Thought pushing through made me tougher, especially on long training rides. Then I started looking at the power files from those sessions. The last hour was always rubbish. I wasn't being tough, I was wasting time and depleting glycogen.

Why shivering changes everything

Shivering can double your metabolic rate. Sounds good, right? More energy expenditure? No. Because shivering burns glycogen, fast. It's your body's emergency heating system, and it runs on your sprint fuel. Once you're shivering, you're not building fitness. You're depleting your carbohydrate stores and sabotaging tomorrow's session.

There's another consideration. When you're not shivering but you're in cool conditions, brown adipose tissue activates. This increases your resting metabolic rate slightly and shifts fuel oxidation towards fat. But that benefit disappears completely once shivering starts. The difference between beneficial cold exposure and destructive cold exposure is whether you're shivering. That's your line.

What shivering tells you

Usually, it means you underdressed. Sometimes it means you went too long. Occasionally it means you didn't eat enough during the ride. Whatever the cause, the solution is the same. Stop. There's no toughness points for finishing an interval set while shivering. You're just making yourself slower.

For ultra-distance riders, this is particularly important. The temptation is to push through on long winter rides because you think you need the time in the saddle. You don't. Not if you're shivering. That's junk miles, and they're counterproductive.

When to Train Outside (And When Not To)

The approach

Get outside once or twice a week when conditions allow. Dry roads, daylight, temperature above freezing. Keep these rides to 60 or 90 minutes. Make them quality, not epic. Use the turbo for your longer sessions, your harder sessions, or when the weather's genuinely dangerous.

I use indoor training for structured work. No shame in that. But I also make sure to get outside when conditions are reasonable. Partly for mental health, partly because riding outdoors maintains the skills and confidence you need for longer events. There's also a physiological reason.

The cellular signal

Research from Dustin Slivka's group shows that exercising in cold temperatures, around 7°C, increases expression of something called PGC-1α. This is the master regulator of mitochondrial biogenesis. It's the genetic signal that tells your cells to build more aerobic machinery. You get this signal training indoors as well, just from the exercise itself. But the cold appears to amplify it. Think of outdoor cold training as an additional stimulus, not a replacement for structured indoor work.

The catch? This is an acute molecular response. To turn that signal into actual fitness requires consistency over weeks and months. It's not a shortcut. It's just another tool.

Be realistic about this

Don't ride in dangerous conditions chasing "cold benefits". Ice, severe cold, no visibility? Stay inside. The marginal gain from cold exposure isn't worth the injury risk or the rubbish training session. Indoor training works perfectly well. But if conditions are reasonable, getting outside adds something. Exactly how much is hard to quantify, but the research suggests it's not nothing.

In British winter, we rarely deal with extreme cold. More often it's damp, grey, and windy. Pick your days. When the roads are dry and you've got daylight, get out. When it's bucketing down and blowing a gale, that's what the turbo is for.

Get Warm Fast After Hard Efforts

The 30-minute window

As soon as you finish, get this done. Strip off immediately. Not after you've put the bike away. Not after you've checked Strava. Now. Hot shower or at least a warm room. Your core temperature needs to come back up. Eat 30 to 50 grams of carbohydrate plus 20 grams of protein. A recovery shake works. So does toast and peanut butter, or a bowl of porridge. Drink 500 to 750ml of fluid. Warm is better than cold, purely because you'll drink more of it.

Why the rush matters

Hard training temporarily suppresses immune function. Research by David Nieman and others has shown this "open window" effect clearly. Your body's first line of defence drops for several hours after intense exercise. Add cold stress on top and you've likely created a bigger immunological challenge. The faster you rewarm and get carbohydrate in, the faster cortisol drops back to baseline. That helps close the vulnerability window.

This isn't theoretical. You probably know this already if you've ever finished a hard winter ride, cooled down slowly, then been ill three days later. The connection is real. For riders training for summer events, getting ill in January or February doesn't just cost you a week. It costs you the cumulative training you'd have done across that week and the recovery period after.

The hydration trap

Here's something most cyclists don't realise. Cold air suppresses your thirst response. The hormone that makes you feel thirsty, arginine vasopressin, doesn't trigger properly in the cold. Meanwhile, you're losing fluid through respiration. Every breath out in cold air is visible moisture leaving your body. Plus cold-induced diuresis means you're losing more fluid through urination. Net result: significant dehydration without feeling thirsty.

Drink by the clock. 500ml per hour, whether you feel like it or not. If your urine isn't pale by evening, you underdrank.

What Winter Training Actually Looks Like

Forget suffering through it. Forget "just getting through to spring". Here's what working with physiology instead of against it means. You ride less than summer, but harder when you do. You dress warmer than feels necessary. You stop before you shiver, not after. You get warm and eat fast. You drink whether you're thirsty or not.

Your power numbers look lower because physics doesn't care about your feelings. That's fine. You're not racing in January. But when March arrives and everyone else is rebuilding base fitness, you've still got your top end. You can go straight into proper training, not spend six weeks remembering how to ride a bike hard.

The research shows block periodisation produces superior adaptations with the same training time. Proper thermal protection prevents a 31% power loss. Cold exposure provides an additional training stimulus for mitochondrial development. The principles work. Apply them consistently and you'll arrive at spring with your fitness intact, possibly improved.

For ultra-distance riders, this approach means you can add volume productively in spring. You haven't spent winter grinding yourself down with long, slow, cold miles. You've maintained your intensity, your steady-state power, and your ability to respond to training stress. When conditions improve and you start building towards your summer event, you're adding volume to a solid foundation, not trying to rebuild everything from scratch.

The Mistakes Everyone Makes

Chasing summer volume in winter conditions. You can't. The conditions don't allow it and your body doesn't need it. Switch to blocks. For ultra-distance riders especially, winter volume is counterproductive. Save it for spring when you can actually complete quality long rides.

Underdressing legs because your core feels warm. Your torso generates heat. Your legs don't. Thermal bibs aren't a luxury item.

Continuing when you're shivering. This is ego, not training. You're depleting glycogen, not building fitness.

Slow cool-down after hard winter efforts. Get warm within 30 minutes. Your immune system notices the difference.

Drinking only when thirsty. Cold suppresses thirst. Drink by the clock instead.

Final Thoughts

Winter training isn't complicated. It's just different. Keep your muscles at operating temperature. Concentrate your intensity into focused blocks. Stop before you shiver. Recover aggressively. Drink by schedule.

Do that and you'll arrive at spring with your fitness intact, possibly improved. The riders who ground out endless slow winter miles will be starting from scratch. Whether you're targeting a local sportive, gran fondo or an Audax, the principle is the same. Winter is about maintaining quality, not chasing quantity. The volume comes later. The choice is obvious really.

For riders with previous multi-week experience from events like Transcontinental Race or Trans America, you know what's coming. For riders stepping up from Paris-Brest-Paris or London-Edinburgh-London, you're entering different territory. Multi-week self-supported riding creates demands that standard ultra-distance training doesn't fully address.

That's not a problem. It's an opportunity to develop new capabilities.

What Makes Multi-Week Different

At London-Edinburgh-London, day three brings cumulative fatigue. You're exhausted, decision-making is impaired, everything hurts. The finish is 12-15 hours away. You can see the end. You push through and it's done.

At NC4000 and other multi-week events, day ten might bring that same fatigue level. You've still got a week ahead. The finish isn't 12 hours away. It's 1,000km and 6-7 days distant. The psychological demand differs fundamentally. When the finish is visible, you can push through almost anything. When it's days away and you're already deep into the effort, you need different mental capabilities.

This isn't about being tougher. It's about developing capabilities matched to sustained multi-week effort. The voice saying "why am I doing this" arrives earlier and stays longer. You're not pushing through to recovery. You're managing ongoing deficit with days still ahead. Having completed LEL doesn't automatically prepare you for this. The mental approach that works on day three of a 1,500km event requires adaptation for day ten of 4,000km when North Cape is still a week away.

That's what makes it interesting.

Training for Multi-Week Physical Capacity

Fitness matters enormously. You need genuine physical capacity to ride 4,000km in two to three weeks. But multi-week self-supported riding demands more than fitness alone.

Physical resilience over extended duration becomes important. Day three saddle discomfort is manageable. Day ten saddle discomfort after a week of cumulative irritation requires different management. Over three days, you push through knowing recovery is coming. Over two weeks, you're managing issues that may develop throughout the duration. Bike fit, nutrition strategies, equipment reliability, sleep management all take on different characteristics over extended periods. Minor irritations can become significant over two weeks.

Many riders experience their most challenging moments around day 8-10. The psychological demand differs from shorter ultras. You're deep into the effort. You're still several days from the finish. In previous ultras, the end was visible by this point. Here, you're managing the middle section of a much longer adventure.

Self-supported logistics adds another dimension. On day one, booking accommodation is straightforward. On day twelve, when you're deep into cumulative fatigue and struggling to think clearly, those same tasks require more effort. Navigation decisions, equipment maintenance, nutrition management, pacing strategy all happen whilst cognitively affected by sustained effort.

Pacing over multi-week duration requires different understanding. Week one can feel deceptively comfortable for well-trained riders. 300km days feel achievable. Individual capacity varies significantly. Elite riders from events like Transcontinental Race sustain aggressive pacing throughout. Others discover their optimal approach involves more conservative week one pacing, building reserve for later stages. Understanding your own capacity requirements for multi-week efforts differs from understanding what works over 3-4 days.

These capabilities are trainable. That's the point.

How Training Differs for Multi-Week Events

Standard ultra-distance training builds capacity for 3-4 day efforts followed by recovery. It works brilliantly for PBP, LEL, and similar events. Multi-week events (NC4000, Transcontinental Race, Trans America, Indian Pacific Wheel Race) demand sustained output for 14-20+ days with only sleep-based recovery. That requires different physiological adaptation.

Training to sustain output over extended periods with incomplete recovery requires different periodisation than training for a single multi-day effort where you push through to full recovery. The psychological preparation that works when the finish is approaching doesn't work the same way when it's still days distant. Managing logistics when fresh is straightforward. Making good decisions about navigation, accommodation, pacing, and equipment when cognitively affected by cumulative fatigue requires practised systems developed during preparation.

Equipment testing needs realistic conditions. Not "can I ride 300km on this saddle" but "what happens over 14 consecutive days with cumulative loading." Not "do my lights work" but "is my charging system reliable for two weeks." What works for four days might develop issues by day ten. Testing protocols for multi-week reliability differ from testing for shorter events.

Learning when to hold back even though you feel strong requires experience. Understanding how much capacity you actually need in reserve for later stages is counterintuitive. These are learnable skills that develop through preparation matched to the demands.

Starting preparation now (if you're registered for an upcoming edition) gives time to develop these capabilities. Waiting until a few months out and training primarily for fitness leaves gaps. Riders without multi-week experience often discover these gaps in Scandinavia, around day 8-10, when they're managing demands their training didn't fully address.

What You're About To Experience

For registered riders, you know the structure from the official website. Self-supported ride from Rovereto, Italy to North Cape, Norway. Mandatory gates at München, Berlin, Gränna, and Rovaniemi. GPS tracking throughout. Time windows for Finisher and Extra Time Finisher titles.

You've read the regulations. You understand it's an adventure structured with proper organisation. If this is your first multi-week event, what might not be immediately clear is how the experience unfolds over extended duration. How the challenges and rewards of week two differ from week one. How the mental and physical experience at day ten with days still ahead creates something different from anything shorter ultras offer.

The event organisers describe it as an experience that can "open your mind and truly change your life." They've created something well-organised with proper infrastructure and real adventure character across Europe. The route is scouted, gates are partially staffed, tracking systems work, the experience is legitimate.

Your preparation determines how you experience it. Not whether you can complete it (many riders with varied fitness levels finish), but how you navigate the challenges and appreciate the rewards.

Coaching for North Cape 4000

Coaching for multi-week self-supported events exists because riders benefit from preparation matched to what sustained multi-week riding actually entails. Fitness is essential. But the complete preparation picture includes capabilities that standard ultra-distance training doesn't fully develop.

Standard coaching for PBP, LEL, and similar events builds capacity for efforts where the finish becomes visible, where you push through to recovery. Multi-week events require additional capabilities.

Training to sustain output over 14-20+ days with incomplete recovery requires different periodisation. The psychological tools that work when the finish is 12 hours away require adaptation when it's 1,000km and 6 days away. Managing daily logistics when cognitively affected by cumulative exhaustion is trainable. Understanding when to hold back even though you feel strong requires specific knowledge about how fatigue accumulates over weeks and what capacity you need in reserve. Equipment selection and testing protocols for multi-week reliability differ from shorter events.

Having completed 14 ultra-distance events including 5th place at Trans Atlantic Way (1,600km self-supported across Ireland), I've experienced what multi-week self-supported events demand. The mental challenges when the finish is still days away, the logistics management under fatigue, the pacing decisions that shape how the adventure unfolds.

Preparation that addresses these elements changes the experience. Not just whether you finish (though that matters), but how you experience the adventure. Whether you're managing crises throughout or navigating challenges you've prepared for. Whether week two becomes survival mode or the continuation of an extraordinary journey.

For riders without multi-week experience preparing for NC4000, examining whether your training plan addresses fitness plus these additional capabilities is worth doing now. The difference isn't usually finishing versus DNF (though preparation affects that). The difference is often experiencing the adventure you're hoping for versus spending week two managing problems you weren't prepared for.

What Riders Say

Riders who complete NC4000 consistently describe it as transformative. Not despite the challenges, but partly because of them. The experience of sustained effort over two to three weeks across Europe creates something different from shorter ultras.

The physical achievement matters. Riding 4,000km self-supported is substantial. But riders often talk about the mental journey, the problem-solving under fatigue, the daily decisions about pacing and logistics, the experience of keeping moving when tired with days still ahead. The capability development that happens throughout the event.

Some bring high fitness levels. Others bring appropriate preparation for what multi-week self-supported riding entails. Often, it's the second group who describe the experience in the most positive terms. They experience the challenges they prepared for rather than discovering gaps during the event.

The organisation has created something well-structured with proper infrastructure. The adventure itself is extraordinary. Your preparation determines how you experience it.

The Adventure Ahead

Over 600 riders are confirmed for the next edition. Some have completed multi-week events before. Others are stepping up from 3-4 day ultras. All are training hard, building fitness, preparing physically.

For riders without multi-week experience, the question is whether preparation addresses what happens throughout sustained multi-week effort. Not just physical capacity (which is essential), but the mental capabilities for when the finish is still days away. The practised systems for managing logistics under cognitive fatigue. The understanding of pacing over extended duration. The equipment testing for multi-week reliability.

Standard ultra-distance training prepares you well for 3-4 day events. Multi-week self-supported events add dimensions that PBP or LEL training addresses partially. The event organisers have created something well-organised with proper infrastructure and real adventure character. Your preparation shapes your experience. Not just whether you complete it, but how you experience one of cycling's great adventures across Europe.

You're about to ride from Rovereto to North Cape. That's extraordinary. Preparation matched to what that actually entails makes it more extraordinary, not less.

We have all been there. It is 3 AM, you are 300km into a 600km audax, and the very thought of an energy bar makes you want to heave. Your stomach feels like a bloated, sloshing lead weight. I’ve been there myself, staring blankly at a petrol station shelf in the middle of the night, physically unable to swallow a single calorie despite knowing I was "bonking."

For years, the community treated these moments as "bad luck" or a lack of mental toughness. But the research into Exercise-Induced Gastrointestinal Syndrome (Ex-GIS) proves otherwise. Your gut is not a static organ; it is a trainable system. If it fails, it isn't because you are "weak"—it’s because you haven't trained it to handle the specific physiological demands of ultra-endurance.

The physiology of the "Blood Shunt" in endurance cycling

To understand how to fix the problem, we have to understand the physiology. During long-duration exercise, your body undergoes a process called splanchnic hypoperfusion. Essentially, your body prioritises survival by shunting up to 80% of blood flow away from the stomach and intestines to the working muscles and the skin for cooling.

This lack of oxygen to the gut (ischaemia) causes the intestinal lining to become more permeable—what is commonly referred to as "leaky gut." Combined with the constant mechanical jarring of the bike and the heat produced by sustained effort, this leads to systemic inflammation, nausea, and the dreaded "slosh" where nutrients sit in the gut rather than moving into the bloodstream.

Ultra-cycling nutrition: Why "eating by feel" leads to failure

Most ultra-riders significantly underestimate the caloric deficit they are creating. A rider moving at a steady endurance pace might burn between 500 and 800 calories per hour. However, the average untrained human gut can only absorb roughly 200 to 250 calories per hour of mixed nutrients.

Over a 24-hour period, that creates a deficit of nearly 10,000 calories. By day three of a multi-day event, that deficit becomes an existential threat to your performance. The only way to survive is to narrow that gap by increasing your Functional Absorptive Capacity (FAC).

Measuring your "Functional Absorptive Capacity" (FAC)

In my coaching practice, we talk about a metric that is arguably more important for ultra-cycling than FTP: Functional Absorptive Capacity.

While FTP tells us what your legs can produce, your FAC tells us how much fuel your gut can actually transport into your bloodstream while under the stress of a 15-hour ride. If your legs can push 200W, but your gut can only absorb enough fuel for 150W, your race has a built-in expiry date.

How we quantify the "Limit"

We don't rely on trial and error. We use a Gut-Stress Field Test to find your specific absorption ceiling. By incrementally increasing carbohydrate intake during a controlled endurance-zone ride, we track the relationship between caloric intake and a Gut Comfort Score.

We are looking for the "Saturation Point." This is the moment where your SGLT1 transporters (the "gates" in your intestinal wall) reach their limit. When this happens, unabsorbed glucose sits in the small intestine, drawing water out of your blood via osmosis. This is the physiological cause of the bloating and nausea that many riders mistakenly attribute to "drinking too much."

How to test your gut: The 3-hour "Step-Up" protocol

If you want to find your current baseline, try this protocol on your next endurance-paced (Zone 2) training ride. Use a 1–10 scale to rate your gut comfort (1 being perfect, 10 being "nausea-induced stop").

Hour 1: Target 40g of carbohydrates (e.g., one large banana + 500ml of standard electrolyte drink).

Hour 2: Increase to 60g of carbohydrates (e.g., one energy bar + 500ml of carbohydrate-mix drink).

Hour 3: Increase to 80g+ of carbohydrates (e.g., two gels + 600ml of carbohydrate-mix drink).

The Result: If your comfort score jumps significantly during Hour 3, you have found your current Functional Absorptive Capacity. This is the ceiling we work to raise through periodised coaching.

The 3-step protocol to an "Iron Gut"

As a coach, my focus is not on prescribing clinical nutrition, but on managing the physiological adaptation of your digestive system. We treat the gut with the same periodisation we apply to your intervals.

1. Upregulating Carbohydrate Transporters - Research confirms that the gut is highly adaptable. Consuming high carbohydrates in training (targeting 60g–90g per hour) increases the density and activity of SGLT1 transporters. By doing this in training, you are literally building more "gateways" for energy to enter your bloodstream.

2. The "Buffer" Training Ride - We integrate specific threshold efforts while following your race-day intake to see how your system responds when blood flow is being pulled away from the gut most aggressively. We want to find your "absorption ceiling" before you reach the start line.

3. Managing Mechanical and Postural Stress - Ultra-cycling involves constant "vertical oscillation." This mechanical stress irritates the gut lining. We look at your core stability and bike fit; a collapsing core in the 15th hour puts immense physical pressure on the gastric system. A better fit is about giving your digestive system "breathing room."

High-altitude gut training for Alpine events

Digestive challenges compound at altitude. At 2,600m on the Galibier, your body processes food differently than at sea level, reduced oxygen affects not just your legs but your entire system, including digestion. For events like L'Etape du Tour (170km, 5,400m of Alpine climbing), you're asking your gut to process substantial calories whilst climbing consecutive passes at altitude when appetite naturally disappears. 

This requires specific gut training: practicing sustained fuelling during long climbing efforts, testing what works when you're hours into a ride and nothing appeals, and developing systems that function when altitude compounds the challenge. Your gut adaptation must match the specific demands of your event. Multi-hour climbing at altitude presents different challenges than flat ultra-distance riding. 

Training your Functional Absorptive Capacity for Alpine climbing conditions means progressive practice during long rides with significant elevation, not just increasing volume on flat routes.

The coach’s perspective: Don’t leave it to chance

I have spent years deconstructing my own "dark zones" and GI failures. What I’ve learned is that a training plan that only looks at Power and Heart Rate is only half a plan.

If you are targeting a major ultra-event, your training must include a protocol for digestive resilience. We need to ensure that when you are 48 hours into a race, your "internal engine" is just as capable as your legs. In my coaching, we build the system so that when the 2 AM wall hits, your body is actually capable of processing the fuel you give it.

Ready to build a more resilient engine?

If you are tired of your stomach being the "limiter" in your performance, let’s change the way you prepare. I work with riders to integrate these scientific gut-training protocols into their seasonal plans, ensuring you arrive at the start line with a system that can go the distance.

1,200 kilometres from Paris to Brest and back. 90 hours to complete it. Several thousand riders from across the globe, all starting within a few days of each other. It's randonneuring's equivalent of a pilgrimage. Riders speak about it differently than other events. But respect and romance aside, PBP presents specific challenges that catch out riders who underestimate what 1,200km across France actually demands.

This isn't about scaring anyone off. It's about understanding what you're signing up for before you book the ferry.

What is Paris-Brest-Paris?

Paris-Brest-Paris is a 1,200km randonnée: a non-competitive long-distance cycling event where riders must complete the distance within a set time limit whilst passing through mandatory controls. The route runs from Rambouillet (southwest of Paris) to Brest on the Brittany coast, then back to Rambouillet. The event covers approximately 1,218km with 11,500 metres of climbing.

You have 90 hours to finish. That's 3 days, 18 hours. Unlike many UK audax events, there's no extended time limit option. 90 hours is what everyone gets.

The event runs every four years, typically in August. Places are strictly limited to 8,000 riders, and the event typically sells out during the priority registration phase. This is why the qualification process matters so much.

PBP isn't a race. There are no prizes, no podiums, no age-group rankings. You're riding for a finisher's medal and the satisfaction of completing something that most cyclists never attempt. But don't mistake "non-competitive" for "easy." The 90-hour limit is tight enough that poor pacing, inefficient controls, or inadequate sleep planning will see you running out of time before Rambouillet.

The Two-Year Qualification Pathway

PBP 2027 requires a two-year qualification process. This isn't like entering a sportive where you simply register and turn up. You need to plan ahead. An experienced audax coach can help guide you through the qualification process with comprehensive audax training plans.

Phase 1: Priority Registration Rides (November 2025 to October 2026)

During 2026, you should ride the longest Brevet de Randonneurs Mondiaux (BRM) distance you can manage. These rides aren't mandatory, but they're effectively essential if you want to secure a place. PBP is limited to 8,000 riders, and spots typically sell out before general registration opens.

Your longest 2026 ride determines when you can pre-register in early 2027:

• Complete 1000km or 1200km in 2026: Priority registration opens mid-January 2027
• Complete 600km in 2026: Priority registration opens late January 2027
• Complete 400km in 2026: Priority registration opens mid-February 2027
• Complete 300km in 2026: Priority registration opens late February 2027
• Complete 200km in 2026: Priority registration opens mid-March 2027
• Complete no qualifying rides in 2026: You're hoping for leftover places after March, which is risky

The message is clear: if you're serious about PBP 2027, you should be riding long brevets during 2026. Without a 2026 ride, you may not get a place at all.

Phase 2: Mandatory Qualification (November 2026 to June 2027)

Once you've pre-registered in early 2027, you must complete a Super Randonneur (SR) series to validate your entry. All rides must be ACP-sanctioned (Audax Club Parisien certified) brevets.

The SR series requires completing four distances:

• 200km brevet (maximum 13.5 hours)
• 300km brevet (maximum 20 hours)
• 400km brevet (maximum 27 hours)
• 600km brevet (maximum 40 hours)

All four must be completed between November 2026 and June 30th 2027. Each ride must have a unique homologation number. You can substitute a longer ride for a shorter one (for example, complete two 600km rides instead of a 400km and a 600km), but you must still have four separate brevet completions with different homologation codes.

Miss the June 30th deadline for your SR series, and you lose your entry despite having paid your deposit and secured your place.

Phase 3: Registration Timeline

• January to March 2027: Pre-register based on your 2026 ride. Pay €50 deposit and select your start group and wave. The 90-hour group (Sunday evening start) is most common, the 84-hour group (Monday morning start) avoids early control congestion, and the 80-hour group (Sunday afternoon start) suits faster riders.
• May 29th 2027: Full registration opens. Enter homologation codes for at least three of your four 2027 qualifiers
• June 12th 2027: Deadline to initiate full registration. Miss this and your reserved spot may be released
• July 4th 2027: Final deadline to upload your fourth qualifying ride code

In the UK, Audax UK (AUK) organises brevets that count toward your qualification. Check the AUK calendar early. Popular 600km rides fill months in advance, and if you miss the limited 600km opportunities in your region during spring 2027, you may need to travel considerable distances to find another before the June 30th deadline. Spring and early summer see the most brevet opportunities; options become sparse by late June.

The two-year process is deliberate. Ride long distances in 2026 to secure your priority registration slot. Complete your mandatory SR series in 2027 to validate your entry. Skip either phase, and you're not riding PBP.

The Control Challenge: Crowds and Chaos

Controls at PBP bear no resemblance to controls at smaller UK audax events.

At a typical 400km UK brevet, a control might be a village hall with 20 riders, a volunteer stamping brevet cards, and perhaps some biscuits. You're in and out in five minutes.

At PBP, controls are secondary schools, sports halls, and community centres temporarily converted into logistics hubs for thousands of cyclists. Arriving at a major control at peak times (particularly evening controls when most riders stop for dinner) means joining queues. Queues for the brevet stamp. Queues for food. Queues for toilets. Queues for the shower, if there are showers. What should take 15 minutes can easily consume 45 minutes or more if you arrive when hundreds of other riders have had the same idea.

Having ridden London-Edinburgh-London twice, I've experienced busy controls, but PBP operates at a completely different scale. LEL has perhaps 500-1,000 riders spread across multiple start groups. Even at Brampton, which sees the heaviest traffic as riders converge from different routes, you're dealing with dozens of riders at a time, not hundreds. The queues exist, but they're manageable. You can usually find floor space to sleep. The food queue moves.

PBP multiplies that by a factor of six or seven. With several thousand riders on the same route hitting the same controls within relatively narrow time windows, the scale of congestion is considerably larger. Major controls become bottlenecks that you cannot avoid but must manage. Based on reports from riders who've completed PBP, the shower queues, sleeping arrangements, and food service all operate under significantly more pressure than LEL controls.

Some riders try to minimise control time by carrying more food and only stopping for the mandatory brevet card stamp. This works on shorter brevets but becomes increasingly difficult over 1,200km. You cannot carry three days' worth of calories, and the mental toll of never properly stopping catches up eventually. You'll need to eat at controls, which means accepting that time spent queuing is part of the event.

The logistics of control stops become critical to your time management. At LEL, I learned that arriving at Brampton slightly off-peak meant finding a sleeping spot more easily and getting better rest. The same principle of timing your control arrivals to avoid peak congestion will apply at PBP, though with a field six times larger, even off-peak periods will be busier than LEL's peak times.

Understanding how to manage control stops efficiently becomes crucial when you're working within a 90-hour limit. Every unnecessary minute spent queuing or searching for facilities is time you're not riding or sleeping properly. This isn't a criticism of PBP's organisation. It's simply the reality of moving several thousand riders through the same infrastructure. But you need to build extra time into your schedule for control stops and accept that efficiency at controls will directly impact whether you finish within 90 hours.

Navigation: Following the Route in France

The route for the 21st edition (August 2027), Paris-Brest-Paris will feature a redesigned, more scenic and rider-friendly route. The route rides a clockwise loop through Brittany to reduce traffic conflicts. 

Stage towns & key checkpoints: Rambouillet · Mortagne-au-Perche · Villaines-la-Juhel · Fougères · Tinténiac · Brest · Loudéac
New additions to the route: Pontivy · Pleyben · Callac · Mont-Saint-Michel viewpoint · Chartres

PBP uses a marked route. Organisers place directional signs at junctions to guide riders. Follow the signs, and you follow the route.

In theory, this sounds straightforward. In practice, particularly during night sections or when fatigued, riders miss signs. Sometimes the signs are small. Sometimes they're placed awkwardly. Sometimes they're removed or damaged.

Most riders use a GPS device loaded with the route as backup. Relying entirely on following the rider ahead is risky. That rider might be lost too, and you won't realise until you're both 10km off-route.

French road signage differs from UK signage. Village names appear on signs, but the smaller hamlets and crossroads you're navigating through may not match exactly what's on your route sheet. Having a rough mental map of the route helps. Paris to Brest is generally west, Brest to Paris is generally east. This helps sanity-check your navigation.

Language barriers exist at controls and in villages. Not everyone speaks English, and at 2am when you're trying to find something or ask a question, communication becomes harder. Basic French phrases help. A translation app helps more.

Some riders report that following the route during the return leg from Brest becomes harder due to fatigue. You've already ridden 600km, you're sleep-deprived, and the roads start looking familiar but aren't quite the same. This is where navigation errors cluster: not on the fresh outbound leg, but on the exhausted return.

Weather: French Climate Variability

August in France usually means warm weather, but "usually" doesn't mean "guaranteed." PBP's route crosses Brittany, a region known for changeable maritime weather. Rain is possible. Strong headwinds coming off the Atlantic are possible. Heat is possible.

Previous editions have experienced both extremes. Some years have seen high temperatures causing dehydration problems for riders. Other years have brought cold, wet conditions with strong winds. Weather can define your PBP experience as much as fitness.

You'll need clothing for both heat and cold. Night temperatures can drop significantly, even in August. The Brittany coast brings different weather than inland areas. What's warm and dry early in the route might be cold and wet 200km later.

Rain gear needs to be functional, not token. If it rains properly, you could be riding in it for 12 hours or more. Cheap waterproofs that work for an hour fail after five hours. Your extremities suffer most in cold, wet conditions, and numb hands at 2am on French country roads aren't just uncomfortable, they're dangerous.

Prevailing westerly winds can make sections of the return leg from Brest slower than the outbound journey. Budget extra time for the return. It's not simply a mirror of the outbound ride.

The 90-Hour Time Pressure

90 hours sounds generous. 1,200km divided by 90 hours is 13.3km/h average, barely faster than walking pace. Surely anyone finishing 600km brevets can manage that?

But 90 hours includes everything. Every control stop. Every meal. Every moment spent queuing for a brevet stamp. Every navigation error. Every sleep period. The actual time you spend riding needs to be significantly faster than 13.3km/h to account for all the time you spend not riding.

Most riders need sleep. Exactly how much varies enormously. Some riders operate on 90-minute power naps, others need 3-4 hour blocks to function. But everyone needs something. If you sleep 4 hours on night one, 4 hours on night two, and 3 hours on night three, that's 11 hours gone from your 90-hour budget. Add 30-45 minutes per control across multiple major controls, and you've lost more hours. You're now looking at riding 1,200km in considerably less than 90 hours, which means your average riding speed needs to be meaningfully faster than 13.3km/h.

The time limit catches riders who haven't practiced efficient control stops, haven't tested their sleep requirements on multi-day rides, or haven't paced conservatively enough early on. By the time you realise you're running out of time, you're often too fatigued to significantly increase your pace.

Multi-Day Fatigue: Beyond Qualification Distance

Completing a 600km brevet proves you can ride 600km. It doesn't necessarily prove you can ride 600km and then ride another 600km.

The fatigue that accumulates over multiple days feels different from single-day fatigue. After 24 hours riding, you stop, sleep properly, recover. At PBP, you get minimal recovery. By day three, cumulative fatigue affects decision-making, bike handling, and motivation in ways that day-one fatigue doesn't.

Simple tasks become difficult. Eating becomes a chore rather than a pleasure. Sleep becomes something you desperately crave but struggle to get properly. The mental fog that descends after multiple days makes everything harder, including the calculation of whether you're still on pace for the time limit.

Physical issues that might be minor irritations on a 400km brevet become serious problems over 1,200km. A slightly uncomfortable saddle becomes unbearable after two days. Hands that feel fine for 12 hours go numb after 40 hours. Minor knee discomfort becomes significant pain.

The hardest part of PBP often isn't any specific section of the route. It's the middle period when you're deep into the event, your body is breaking down, and the finish still feels distant.

Nutrition and Hydration: The Three-Day Challenge

Fuelling 1,200km over multiple days presents different challenges than fuelling a single 600km brevet.

On a 600km ride, you can afford to under-eat slightly and make up the deficit afterwards. Over three days at PBP, cumulative calorie deficits catch up. You're burning 4,000-6,000 calories per day whilst trying to consume enough to keep functioning. By day two, many riders struggle to eat at all. Foods that tasted good on day one become unappealing. Your appetite diminishes precisely when you need calories most.

Control food at PBP is substantial. French controls typically offer hot meals, soup, pasta, bread, cheese, fruit, and sweet options. The food is good, but you're eating it whilst exhausted, often at 2am, surrounded by hundreds of other riders. What should be a pleasant meal becomes functional refuelling.

The challenge isn't just calories. It's maintaining hydration across multiple hot August days whilst managing electrolyte balance. It's eating enough at each control without overloading your stomach before riding. It's carrying sufficient backup food for the 80-100km between controls without weighing yourself down. It's forcing food down when you're not hungry but know you need it.

Some riders develop their nutrition strategy through trial and error on qualification rides. Others arrive at PBP having never practiced three consecutive days of riding and eating. The difference shows by Brest. Riders who've tested their multi-day nutrition systems know what foods they can tolerate when exhausted, how often they need to eat, and how to balance control meals with carried snacks. Those who haven't often struggle with energy crashes, digestive issues, or simply not eating enough to sustain the effort.

This isn't about having the perfect nutrition plan. It's about having practiced enough to know what works for your body across multiple days of hard riding. The 600km qualifier doesn't teach you this. Systematic preparation does.

International Logistics: Getting to France

You're riding in France, which means getting yourself and your bicycle across the Channel.

Ferry options include Dover-Calais, Portsmouth-Caen, and Portsmouth-St Malo. Some riders drive to France, others take the Eurostar to Paris then travel to Rambouillet. Whatever option you choose, factor in bike transport logistics. Trains may require bikes to be bagged or boxed, ferries usually allow bikes but check capacity and booking requirements in advance.

Rambouillet is southwest of Paris, roughly 50km from the capital. Accommodation in Rambouillet fills well in advance. Some riders prefer to stay in Paris and travel to the start on event day, though this adds complexity when you're already preparing for a 1,200km ride.

Understanding Start Groups and Time Limits

PBP uses three start groups, each with different departure times and time allowances:

90-Hour Group (most common): Starts Sunday August 22nd between 17:45 and 21:00. This is the standard group for most riders, offering the most buffer for sleep and mechanical issues. Most riders choose this option.

80-Hour Group (fast riders): Starts Sunday August 22nd between 16:00 and 17:00. For experienced riders who can maintain higher speeds and manage minimal sleep. This earlier start means you're ahead of the main field.

84-Hour Group (daylight preference): Starts Monday August 23rd between 05:00 and 06:00. For those who prefer to sleep Sunday night and ride mainly in daylight hours. Starting Monday morning means fewer crowds at the first controls as you're riding behind the main bulge of Sunday starters.

Your choice of start group determines your entire race strategy. The 90-hour group faces the heaviest congestion at early controls (Mortagne, Villaines, Fougères) as thousands of riders hit these points simultaneously. The 84-hour group avoids this congestion but has less time overall. The 80-hour group starts earliest but requires the fastest pace.

The Wave Start System

Within your chosen start group, riders are released in waves of approximately 300 riders every 15-20 minutes. Waves are designated by letters (Wave A, Wave B, etc.). You select your specific wave during registration, which is why pre-qualifying with a 2026 ride matters: it grants early access to select the most desirable wave times within your chosen group.

Tandems, triplets, and recumbents typically have dedicated waves. There's also traditionally a women's wave on Sunday at 17:15 for those who wish to ride together.

Your clock starts the moment your wave crosses the starting mat and doesn't stop for sleep, meals, or repairs. Each control point has specific closing times, typically spaced every 80-100km. Arrive after a control has closed, and you're disqualified regardless of how much time remains on your overall limit.

Mandatory Equipment

Before you're allowed to start, you must pass a bike check in Rambouillet. Required equipment includes:

• Front and rear lights (permanently fixed, not removable)
• Backup lights for both front and rear
• Reflective vest meeting EN ISO 20471 standards
• Helmet (mandatory for the entire event)

Fail the equipment check, and you won't be allowed to start. Check the official PBP equipment list well before the event as requirements may be updated.

Currency is euros. Your UK bank card works but check foreign transaction fees. Having cash for controls helps. Not all accept cards, especially smaller controls in rural areas.

Is PBP Right for You?

Paris-Brest-Paris isn't the natural next step after completing a 400km brevet. It's several significant steps beyond that.

You should be comfortable riding 200-300km regularly. Not occasionally. Regularly. The 600km qualifier gives you a sense of distance, but PBP doubles it and adds international logistics, larger crowds, and tighter time management.

You need to have tested your ability to function on limited sleep across multiple days. One night of disrupted sleep is manageable. Multiple nights of minimal sleep whilst continuing to ride requires knowing how your body responds and how much sleep you actually need.

You should be confident navigating in unfamiliar areas, ideally using both GPS and map reading. Getting lost costs both time and mental energy.

If you haven't ridden multi-day events before, gaining that experience before attempting PBP makes sense. Qualifying brevets are single-day events. PBP is multi-day. The skills aren't identical.

None of this means PBP is impossible or that you shouldn't attempt it. Thousands of riders successfully complete it every four years, including many doing it for their first time. But they're the riders who understood what they were signing up for, prepared systematically, and respected the distance.

PBP rewards preparation, conservative pacing, and robust systems for managing controls, sleep, and nutrition. It punishes overconfidence, poor planning, and underestimating what 1,200km across France actually demands. If you're ready to commit to PBP 2027 and want structured support through both the 2026 priority rides and 2027 qualification series, event-specific coaching for Paris-Brest-Paris can guide that preparation systematically.

Preparing for PBP: Beyond the Qualification Rides

Completing your Super Randonneur series proves you can ride the distances. It doesn't automatically prepare you for the multi-day fatigue, control management, and pacing discipline that PBP demands.

The riders who finish strong are those who've practiced sleeping with hundreds of other riders around them, tested their nutrition over consecutive long days, and developed conservative pacing strategies that work for 1,200km, not just 600km. They've ridden overnight multiple times. They've navigated when exhausted. They've managed multi-day fatigue, not just single-day efforts.

The SR series qualifies you to enter PBP. Systematic multi-day preparation gets you to finish. If you want structured preparation that addresses these demands, not just the qualification requirements, Paris-Brest-Paris coaching provides the framework.

Your Timeline for PBP 2027

If you're considering Paris-Brest-Paris 2027, here's your timeline:

2026 (Priority Registration Phase): Ride the longest BRM distances you can during 2026. Aim for 600km or longer to secure early priority registration in January 2027. Without a 2026 ride, you risk not getting a place at all.

Early 2027 (Pre-Registration): Based on your longest 2026 ride, pre-register during your allocated window (January to March 2027). Pay your €50 deposit and select your start group and wave. The 90-hour group (Sunday evening start) is most common, the 84-hour group (Monday morning start) avoids early control congestion, and the 80-hour group (Sunday afternoon start) suits faster riders.

November 2026 to June 2027 (Mandatory Qualification): Complete your Super Randonneur series: 200km, 300km, 400km, and 600km brevets. All must be ACP-sanctioned rides with unique homologation numbers. Don't leave your 600km until late spring. The deadline is June 30th 2027, and if you fail a late attempt, there won't be time for another.

May to July 2027 (Final Registration): Upload your SR series homologation codes by the deadlines (May 29th for three rides, July 4th for the final ride). Miss these deadlines and you lose your place despite having qualified.

August 2027: Ride 1,200km across France. Return to Rambouillet within 90 hours. Collect your finisher's medal.

The registration will open, and thousands of riders will commit to something genuinely difficult. Make sure you're ready for what you're committing to.

Read our Paris-Brest-Paris coaching guide that prepares you for the the challenges.

Bike fit: it's important for good reason
Your bike fit must be dialled in for ultra-distance efforts. Position issues barely noticeable during 3-hour rides become significant at 8 hours, genuine problems at 12 hours, and potentially event-ending at 18+ hours.

Professional fitting is non-negotiable: Investment in a proper bike fit. I recommend this for all my coached riders. It's that important.

Test with full load: Your bike handles completely differently when loaded with gear. Do your longer training rides with everything mounted and loaded.

Here's where I disagree with some: I tell riders to prioritise comfort over aerodynamics. The fastest position is the one you can sustain for 16 hours a day, not the one that saves you 10 watts in a wind tunnel.

Nutrition: forget everything you think you know
Daily energy expenditure reaches 8,000 calories during 16-hour riding days. You can realistically consume maybe 3,500-4,000 calories without digestive rebellion. For post-event recovery, specific protein and carb targets help rebuild what these massive efforts deplete.

Most coaches will tell you to optimise macronutrients and time feeding perfectly. I take a more flexible approach after watching too many riders fail with "perfect" nutrition plans.

Practise eating without appetite: By hour 8, food becomes unappealing. At hour 12, even familiar foods trigger nausea. Yet energy intake remains essential.

In those cases I tell riders to ignore nutrition plans entirely. If you're craving a McDonald's cheeseburger at hour 14, eat the cheeseburger. In fact, eat two of them. Your body knows what it needs better than any plan.

My approach: Ultra-distance nutrition prioritises calories by any means necessary. I've had riders succeed on chocolate milk, petrol station sandwiches, and ice cream because that's what they could stomach. During the event itself, energy management and pacing become the primary concerns for multi-day success. The nutrition police hate this, but finish line riders don't care about optimal macronutrient ratios.

Sleep management: the skill nobody talks about properly
Most sleep advice focuses on duration, but I've learned timing matters more. Understanding why rest builds fitness helps frame sleep as performance tool rather than weakness. Some riders need 4 hours in one block; others function better on two 90-minute periods. Individual variation is enormous.

Plan minimum requirements: Most successful ultra riders need 2-4 hours nightly to maintain safe function. But some can function on 90 minutes and others need 5 hours. Practise in training to find what works best for you.

Master strategic napping: Twenty-minute power naps often provide more recovery than longer sleep periods when operating under time constraints.

Carry emergency sleep gear: Even when planning accommodation, carry lightweight bivouac gear. A basic system weighs under 2kg while providing crucial flexibility.

I'm still learning about sleep management, both from my own experience and from working with coached riders, and I'm convinced sleep strategy is more individual than any other aspect of preparation.

Electronics and power management
It's possible to get quite nerdy about power management but this is important. I've seen too many good rides ended by dead batteries - including rides of my own.

Calculate realistic power requirements: GPS units consume 15-20Wh during 16-hour operation. Lighting adds 10-15Wh. Phone usage, satellite trackers typically total 40-60Wh daily consumption.

Select charging methods: Dynamo hubs provide 3-6 watts continuous generation but require compatible equipment. Battery banks offer 10,000-20,000mAh storage but add weight. Mains charging works but requires route planning around availability.

Here's where I'm probably more paranoid than necessary: I always recommend two independent charging systems. Yes, it's overkill but when one fails you'll be thankful you have the backup.

Weather preparation: expect the worst
Always prepare for worse conditions than forecast because weather predictions beyond 3 days are essentially guesswork.

Protect electronics from precipitation: Test waterproofing by putting devices in sealed bags and exposing them to a lot of water. It sounds extreme, but "waterproof" equipment fails more often than manufacturers admit.

Manage heat and cold: Cold weather decreases battery performance so plan ahead if you know your event is in cold climates.

Common preparation oversights
Inadequate system integration testing: This is the mistake I see most often. Riders test their GPS, test their lights, test their bags but never test them all together during a 12-hour ride.

Underestimating time requirements: Plan for 75% riding time, 25% for everything else that takes longer than expected.

Equipment overconfidence: Gear comfortable for 6-hour rides may become problematic after 12+ hours.

Sometimes I tell riders to deliberately create problems during training to help learn how to solve problems when they're manageable and prepare you for when they become critical.

My coaching approach: prevention over optimisation
My philosophy has evolved significantly over the years. I started out focusing on optimisation trying to find perfect positions, ideal nutrition timing, and efficient training protocols. But now I've moved away from that rigid approach.

Now I prioritise prevention over optimisation. I'd rather have a rider finish successfully with suboptimal equipment than abandon with perfectly optimised gear they haven't properly tested.

The coaching process begins 6 months before target events, allowing time for bike fitting, equipment testing, and skills development. For time-crunched athletes, building endurance with limited training hours requires strategic session selection and quality focus. We identify potential failure points specific to your event and individual characteristics, then develop targeted solutions. My approach emphasises robustness over efficiency.

Essential preparation checklist

[  ] Lighting: primary and backup systems with spare batteries
[  ] Sleep system tested if required
[  ] Repair kit customised for your specific setup

Final preparation tasks:
[  ] Route loaded and verified on all devices
[  ] Weather forecasts checked, equipment adjusted accordingly
[  ] All bookings confirmed, emergency contacts programmed
[  ] Nutrition strategies tested during longest training efforts
[  ] Waterproofing tested in sustained wet conditions

The foundation of success
Ultra-distance cycling success depends on thorough preparation addressing the complete challenge, not just physical demands. Events are decided by preparation details: correct bike fit, practised nutrition strategies, reliable electronics, and appropriate fatigue recognition.

The strongest riders aren't necessarily those who finish successfully. Success belongs to those who've prepared systematically and understand that avoiding problems often matters more than optimising performance.

This preparation process can seem overwhelming when approached individually. Working with an experienced coach provides structure, accountability, and personalised guidance that addresses your specific requirements.

If you're considering an ultra-distance challenge and want systematic preparation support, I'd welcome the opportunity to discuss how coaching can help you achieve your goals safely and successfully. The investment in proper preparation almost always determines the difference between a successful adventure and an expensive disappointment.

Riders tend to be good at pushing on. We are used to being tired. We expect discomfort. Many of us even take a kind of pride in carrying on regardless. But illness is not the same as fatigue. It is not a signal to push through. It is your body asking for space to heal. When you are fighting something off, even mild symptoms can tip the balance. Riding anyway might feel fine in the moment, but it can draw out your recovery, deepen the fatigue or trigger a setback that takes much longer to recover from. What feels like a brave decision in the morning can turn into a frustrating two-week stop that could have been avoided with one quiet rest day.

There is a rough rule of thumb known as the neck rule. If your symptoms are above the neck, like a runny nose or a mild sore throat, and you otherwise feel okay, you might get away with a gentle ride. But if the symptoms are below the neck, like a chesty cough, muscle aches, or any fever, you are better off staying off the bike. Even in mild cases, the real test is how you feel after. If a short spin leaves you feeling worse, it was too much. There is no fitness gained by overriding your immune system.

What is usually behind the urge to ride is not stubbornness but fear. Fear that the progress you have made will disappear. That time off will undo all the work. But the science is reassuring. You can miss a week of training without any meaningful drop in aerobic fitness. The adaptations that matter most for distance riding, the deep aerobic base, metabolic efficiency, mental resilience, those do not vanish in a few days. (For more on why rest builds fitness rather than destroys it.) If anything, short breaks can actually help. They give your system space to reset, especially if you have been stacking fatigue for weeks. I have seen athletes come back stronger after illness, not because they trained through it, but because they rested properly and returned with a fresh perspective.

When it comes time to get back on the bike, keep it simple. Your body will usually give you a clear signal. Your resting heart rate comes back to baseline, your sleep improves, your mood lifts, and you start to feel a genuine urge to move again. That is when you can test the waters. Begin with something light and short. No structure, no targets, just easy pedalling at Zone 1 intensity. Treat it as a conversation with your body. If it feels good, you can continue. If it does not, wait another day. One quiet day now is always better than ten forced days later.

Here is a way to ease back in. For the first few rides, keep the duration short and the intensity very low. Think of it as active recovery, not training. Focus on how your breathing feels, how your legs respond, and how you feel afterwards. If everything checks out, you can gradually build duration. After three or four solid rides with no setbacks, you can start to fold in light structure. But avoid the trap of trying to make up for lost time. There is nothing to catch up on. Fitness is not built in a single session. It is built in rhythm.

If illness becomes a regular disruption, it is worth stepping back to ask why. Sometimes it is just bad luck. But often there are clues. Are you fuelling properly during your long rides? Is your recovery matching your training load? (See post-ride recovery protocols for sleep, nutrition, and monitoring guidelines.) Is stress outside training piling up without you noticing? These are all things that chip away at resilience. You do not need to overhaul everything. Just notice the patterns. Take the feedback and make a small adjustment. Your immune system is part of your training too.

There is no glory in pushing through illness. The strongest riders are not the ones who train no matter what. They are the ones who listen, adapt and respond. Rest is not time lost. It is part of the work. When you treat it with the same respect you give to intervals and endurance blocks, you stop fearing it. You start to trust that you are not losing fitness by resting, you are protecting it.

So next time you feel something coming on, take a step back. Give your body a chance to do what it needs. The road will still be there. And when you come back to it, you will ride with a little more calm, a little more patience, and a deeper trust in your own judgement.

Go out too hard and you might feel like a hero for a few hours. But ultra riding isn’t about the first few hours. It’s about the quiet middle, the long grind in the dark, the cold mornings when your legs feel like planks. Pacing is what holds it all together.

This isn’t about riding slow. It’s about riding smart.

Stop thinking about speed. Start thinking about energy
Speed is a vanity metric in ultra distance. It changes with wind, terrain, temperature, traffic. Try to chase it, and you’ll end up burning more energy than you can afford.

Instead, treat energy like a budget. You’ve only got so much each day. Use it all before the last climb, and that climb will chew you up and spit you out. Ride steady, save your matches, and you’ll have something left when it matters.

Here’s a rule worth remembering: if your breathing’s heavy and your legs are biting back, you’re overdoing it. Doesn’t matter what your average speed says. Doesn’t matter how fast the rider next to you is going. Your job is to last, not to win the morning.

Heart rate, power, and perceived effort — pick your weapon
If you train with power, great. If you prefer heart rate, also fine. If you go by feel, you’re in good company. What matters is understanding what “sustainable” actually feels like.

As a guide:

• Power: Around 60 to 70 percent of your threshold, though that’s a ceiling not a target
• Heart rate: Usually low Zone 2, somewhere between 60 and 75 percent of your max
• Perceived effort: Think 4 out of 10. Calm breathing, no strain, legs ticking over without tension (similar to proper easy ride intensity)

The mistake most people make is treating this like a steady zone to hold. In reality, it’s about restraint. You’ll have moments when you feel invincible. That’s when you need to back off the most.

One more thing, keep an eye on heart rate drift. If your heart rate keeps creeping up while your power stays the same, your body’s working harder than it should. Take that seriously.

Multi-day pacing starts the night before
People always ask about what to eat, what to pack, what to wear. But one of the biggest things that affects how you pace is how you sleep.

Ride too hard and your body won’t shut down properly. Your heart rate stays high, your digestion goes haywire, and you wake up groggy even after seven hours in a bivvy bag. That fatigue compounds day after day. (Learn more about why rest and recovery build fitness.)  Before you know it, you’re dragging yourself through the morning miles with zero appetite and a headache that won’t go away.

If you finish a day’s ride and your heart’s still racing 90 minutes later, it’s a clear sign you overcooked it.

Good pacing gives your body the best shot at recovery. That means lower post-ride stress, calmer digestion, and a better shot at actual sleep — not just lying down for hours hoping to drift off.

Fuel follows effort, not the other way around

You can eat all the right food and still bonk if your pace is wrong. That’s the part people often miss.

Go too hard and your body leans heavily on carbs. But your gut can only process so much, especially when it’s stressed. (For comprehensive post-ride recovery nutrition protocols, including protein and carb timing.) That’s when you get nausea, bloating, or that sudden drop where everything feels wrong. It’s not always the food’s fault. Sometimes your effort is the problem.

The fix? Ride at a level that lets you burn more fat. That takes pressure off your digestive system and spreads the load. You’re not trying to be low carb. You’re trying to be steady enough that your body stays calm.

Basic fuelling principles still apply:

• Eat early, before you’re hungry
• Eat often, small, regular snacks beat giant stops
• If your stomach starts complaining, ease off before blaming the food

The golden rule: if your gut goes quiet, listen.

The emotional side of pacing
Here’s the bit that catches people out: pacing isn’t just physical. It’s emotional.

You’re fresh, the sun’s out, your legs feel good. Of course you want to push a bit. But pushing a bit when you feel strong is exactly how you ruin the second half of your day.

Or maybe someone passes you. They’re spinning up a climb and you don’t want to be left behind. That’s pride talking. And pride doesn’t care if you hit a wall six hours later. (This is similar to staying present and managing your mental game during endurance efforts.)

The best riders set pacing strategies before they even roll out. They know what they’re going to ignore. They know what’s worth chasing and what isn’t. And they stick to it, even when it feels too easy, or too boring, or too slow.

Trust me: restraint is a performance tool. It just doesn’t come with numbers or kudos.

Train pacing like a skill
You can’t learn pacing from reading about it. You have to feel it in your body, and the only way to do that is to practise it.

That means training rides where the goal isn’t speed, but consistency. Long sessions back to back. (For structured approaches to building endurance without massive volume, see how time-crunched riders build serious endurance.) Rides that start slow and stay slow. Sessions where you dial in fuelling, monitor how your body reacts, and notice what effort feels like after six hours in the saddle. These principles form the core of effective audax training plans.

You’ll start to recognise little signs like your hands swelling more when you push too hard, or your appetite fading when you’re skating the edge. These are the things no training plan can teach. You’ve got to live them. These pacing principles are essential for gran fondo events like Mallorca 312 and La Marmotte.

Five ways to know you’re pacing too hard
Pacing errors sneak up on you. But there are clues. Watch for:

1. Rising heart rate for the same effort
2. Food sitting heavy or appetite vanishing
3. Sleep that feels shallow or fragmented
4. Brain fog, mood swings, or poor decisions
5. Legs that feel flat within the first hour

One on its own? Maybe just a bad day. Two or more? Ease off. You’re burning more than you can replace.

One last thing
You’re not riding to impress your bike computer. You’re riding to stay in the game. Multi-day efforts don’t reward the strongest rider. They reward the smartest one. The one who knows when to push and when to hold back. The one who finishes each day with just enough left in the tank to go again.

That’s the art. That’s the challenge. And that’s what makes it worthwhile.

If you’re gearing up for a big ride and want help building a pacing plan that actually works, get in touch. There’s no one-size-fits-all but there’s always a smarter way to ride. Learn more about audax coaching for ultra-distance preparation.

Most rider don't have the luxury of time to do massive hours on the bike to train for ultra-distance events, however,  the trick isn’t more hours. It’s better hours, and fuelling those hours properly.

Why endurance isn’t just about long rides
The goal with aerobic endurance is to build your ability to ride for hours without falling apart. That means improving your fat oxidation, sparing glycogen, regulating blood sugar, and making sure your muscles and brain stay switched on deep into a ride.

That doesn’t just happen through volume. You can get a lot of those adaptations through targeted training sessions that stress the aerobic system without needing to ride forever.

But here’s the catch: if you’re only training 8 to 12 hours a week, every session matters. And the only way to consistently get the most out of each ride is to support it with the right fuelling before, during and after.

A weekly training structure that works
Here’s a simple example of how a week might look for a time-crunched endurance rider:

• Two tempo sessions - These are your workhorse sessions. You might ride 2 x 20 minutes at low Zone 3, with 5 to 10 minutes recovery in between. Or 3 x 15 minutes. The effort feels steady and strong — you’re breathing harder but you could still hold a conversation in chunks.
  Fuel tip: Start with carbs before the session (30 to 50g), and sip a carb drink or take a gel halfway through. The goal is to avoid a dip in output during the final effort.
   
• One to two steady Zone 2 rides - These might be 60 to 90 minutes midweek. The effort should feel easy, but don’t let your focus drift. This is true easy riding at conversational pace where you can chat freely without breathlessness. You’re training the aerobic system to be more efficient — that means keeping the power and heart rate in check.
  Fuel tip: If it’s under 90 minutes and you’re well-fed, you can ride these without carbs. But doing them fasted is rarely a good idea if you’ve got more sessions coming. Think about the whole week, not just one ride.
   
• One longer ride (weekend) - This is your chance to go 3 to 5 hours if time allows. It should mostly be Zone 2, but you can include 2 x 20 minutes at tempo in the final hour to simulate riding under fatigue. If you're building towards multi-day ultra events, understanding energy management principles becomes even more critical with limited training time.
  Fuel tip: Aim for 60 to 90g of carbs per hour. That’s more than most riders think. Use a mix of drink mix, gels and real food if needed. Practise what you’ll use in events — this is as much about gut training as it is leg training.
   
• Optional recovery spin - These short, low-intensity rides are mainly about keeping the legs moving and staying in the habit.
  Fuel tip: Not essential here. Just make sure you’re well-fed going in and focus more on hydration.

These time-efficient principles are exactly what I use when coaching riders for major Alpine sportives like L'Etape du Tour. A 170km route with 5,400m of climbing over legendary cols like the Galibier and Alpe d'Huez demands serious endurance, but most riders preparing for L'Etape can't train 30 hours weekly. The systematic approach outlined above - quality over volume, strategic intensity, and smart recovery - builds the climbing endurance and multi-hour capacity needed for L'Etape without requiring unrealistic training volumes.

Nutrition makes or breaks your week
Training breaks you down. Nutrition is what builds you back up. If you’re training on limited time, your margin for error is even smaller — you have to recover properly between sessions. Follow science-backed recovery protocols for sleep, nutrition targets, and monitoring to maximize adaptation from limited volume.

That means:

• Daily energy intake needs to match training load - Don’t underfuel on rest days to chase weight loss. You need the calories to recover. Spread carbs across meals, not just around training.
• Protein every 3 to 4 hours - You’re aiming for 20 to 30g of high-quality protein per meal or snack. This supports muscle repair and keeps energy stable.
• Carbs are your fuel, not the enemy - Low-carb strategies have their place, but not if you’re trying to build endurance with limited training hours. You’ll just end up under-recovered and flat.
• Hydration isn’t just about water - Include electrolytes, especially after sweaty indoor sessions or longer rides. Even mild dehydration hits performance and slows recovery.

One final thought
If you’re training 10 hours a week, you’re already making a serious commitment. Don’t let poor fuelling waste that effort. I’ve seen it so many times — riders smash a tempo session then skip lunch. Or go long on Sunday then eat like it was a rest day. Over time, that catches up with you. You lose quality, you burn out, and eventually, you plateau. Training is just one part of the picture. Nutrition is the glue that holds it together.

Want help tailoring this to your riding? I coach riders who need to balance work, kids and everything else around their riding. 

The truth is, the ability to ride easy and not let your ego get in the way is one of the clearest signs of a mature athlete. And when I say easy, I don’t mean cruising just under threshold and calling it recovery. I mean zone 1 or low zone 2. The sort of ride where you could eat a flapjack and hold a conversation the entire time. Not just a sentence or two. A whole chat. Think: “I could be out with my mum and still not look like I’m trying.”

Easy rides are how the body learns to absorb training

This is the part that often gets missed. Training doesn’t make you stronger. Recovery from training does. If all you do is smash sessions and stack up intensity, you’re eventually going to burn out or hit a plateau. Your body never gets the chance to adapt.

Easy rides create space. They help your cardiovascular system stay sharp without adding muscular fatigue. They nudge along blood flow, clear waste products, encourage oxygen delivery to tissues. This is why post-ride recovery protocols emphasize Zone 1 rides in the days following hard efforts. All the behind-the-scenes work that’s essential if you want to come back stronger.

When you look at a properly structured plan, it’s not just a bunch of hard sessions. It’s a blend. Intervals, long rides, gym, skills work, rest days, and yes, those deceptively dull easy rides. They’re often placed the day after something tough or leading into a race block. Think of them like active recovery. A way to keep things ticking over without adding more stress.

They build aerobic depth

You know that feeling when you’re six hours into a ride and still feel like you’ve got something left? That’s not magic. That’s aerobic base. And a solid aerobic engine is built not on hero efforts but on consistency and volume. Volume you can only safely accumulate if a decent chunk of your riding is low intensity.

It’s how WorldTour riders can clock up 25 to 30 hours a week and still hit their targets. They’re not drilling it every time they swing a leg over the bike. For multi-day ultra-distance events, this ability to ride at sustainable intensity becomes non-negotiable. A lot of those hours are easy. Coffee spin pace. Fat-burning, endurance-building, tendon-friendly pace.

Easy rides for Alpine endurance

For riders preparing for multi-pass Alpine events, easy rides build the aerobic foundation that sustains power on consecutive climbs. L'Etape du Tour demands climbing capacity across the Croix de Fer, Galibier, and finally Alpe d'Huez when you're already fatigued. This requires an aerobic base that only months of consistent, mostly-easy riding can develop. The riders who race early cols and suffer by Alpe d'Huez typically haven't built sufficient aerobic foundation. Those who finish strong have done the boring, unglamorous base work. Sprint intervals won't prepare you for 8+ hours of sustained effort at altitude. Easy rides will.

When you’re returning from injury, easy is essential

This is a big one. If you’ve been off the bike for a while with a knee niggle, back pain, whatever it is, jumping straight back into intervals is a brilliant way to go straight back to physio.

Easy rides are the bridge. They’re how you get movement back into the system, test tolerance, gently reintroduce volume. Similar principles apply when returning from illness using gradual progression without pressure. You’re rebuilding tissue strength, coordination, confidence. It’s not sexy, but it works. I usually start with short, frequent, zone 1 rides. No power targets. Just feel. We build from there.

And it’s not just physical. There’s something psychologically valuable about moving again without pressure. Getting your rhythm back. Easing that anxiety that often comes after time off. Athletes are terrible at rest. Easy rides give you a low-stress way to start again.

It’s also about the headspace

I ride easy when I need to think. When I’ve had a long week, or there’s a problem I’m stuck on, or I just want to enjoy the act of turning pedals. You notice more when you’re not working hard. The seasons changing. New roads. That weird pub you’ve passed a hundred times but never really looked at. There’s something deeply good about those kinds of rides.

I tell the riders I coach to treat them like meditation with wheels. No pressure. Just ride. Mental training for endurance ride] often starts with this ability to stay present without chasing performance.

The trap of always doing too much

If you track your rides you’ll probably know what I mean when I say “performing for the feed.” That little voice in your head telling you not to upload a ride if it doesn’t look impressive. It’s rubbish, of course. But it’s powerful.

Coached athletes get around this by knowing the why. When a ride is easy on purpose, it becomes meaningful. Not something you’re embarrassed about. And often those are the sessions that set you up for a personal best in a month or two. Because your body’s ready. Because you haven’t cooked yourself trying to win imaginary internet points. Understanding why rest builds fitness helps you resist the urge to do more when less is smarter.

What an easy ride looks like in practice

For most people, easy means somewhere between 50 and 65 percent of your FTP. If you’re using heart rate, you’re probably in zone 1 or low zone 2. If you’ve got neither, use your breathing. You should be able to talk easily and never feel breathless. Legs should spin freely. No tension. No chasing anyone up a hill.

Duration depends on the rider and the goal. Sometimes it’s 45 minutes just to shake out the legs. Sometimes it’s three hours at a steady endurance pace. But the common thread is that you get off the bike feeling better than when you got on. You’re not drained. You’re recharged.

Learn to love them

If there’s one thing I’d say to every athlete who wants to get better, it’s this: learn to embrace the easy days. They’re not a sign of weakness. They’re part of the work. Just because you’re not suffering doesn’t mean you’re not getting better.

Honestly, some of my favourite rides have been the ones with no goal beyond spinning the legs and watching the world go by. Because that’s where the real gains come from. Not just the work you do, but how well you recover from it. Have you been making space for that in your training?
