The Three Peaks Cyclocross is not a cyclocross race. It is not a sportive. It is not a fell race, either, although it has more in common with fell running than anything else in the British cycling calendar. It is something entirely its own — 61 kilometres across the Yorkshire Dales, up and over Ingleborough, Whernside, and Pen-y-ghent, with a bike on your shoulder for the sections that would defeat a mountain goat on a good day. Late September. Wind. Rain. Mud. Limestone. Roughly 1,500 metres of climbing, a significant chunk of which you do on foot.
There is no other event in British cycling like it. The closest comparison might be a Belgian cyclocross race crossed with a Lake District fell race, except the distances are longer, the terrain is rougher, and nobody is handing you a pressure washer at the halfway point. You ride road sections between the peaks, race cyclocross-style through fields and farm tracks, then shoulder the bike and run — or hike, or scramble — up fell sides where the gradient hits 30-40% and the footing is wet grass over limestone.
Here is the thing. Most riders who enter the Three Peaks prepare like cyclists. They do interval sessions, they build FTP, they ride their CX bike on grass once or twice. Then they hit the first carrying section on Ingleborough and realise that no amount of threshold work prepares a body for running uphill with a 9kg bike digging into the shoulder. The riders who finish well are the ones who trained like hybrid athletes — part cyclist, part fell runner, part pack mule.
This guide covers 12 weeks of preparation built around the demands that actually decide your finish time.
Key Takeaways
- Three Peaks Cyclocross is a fell race with a bike — training like a pure cyclist will not prepare you for the carrying and running demands
- Running fitness matters as much as cycling fitness, with 40-50 minutes spent on foot across the three climbs
- Shoulder conditioning for bike carrying is the most neglected preparation area — build from 10-minute carries to 25-30 minutes
- CX descending skills on wet, rocky terrain separate mid-pack from back-third finishers
- Late September Yorkshire Dales weather demands proper kit planning for rain, wind, and near-freezing summits
- Shoe choice is a genuine race decision between pedalling efficiency and carrying/running grip
- The 12-week build splits into Base + Running, Build + Carrying, and Specific + Taper blocks
What the Three Peaks Actually Demands
The route runs roughly west to east across the Dales, linking three peaks that fell runners and hikers will know well. Each one presents a different problem.
Ingleborough (723m). The first peak and the one that breaks the most unprepared riders. The approach is rideable to a point, then the gradient kicks up and you are off the bike and carrying. The climb itself is steep, grassy, and exposed. The descent is fast and technical — rocky singletrack and limestone steps that punish anyone without bike handling skills. This is where you discover whether your shoes grip and whether your brakes work in the wet.
Whernside (736m). The highest of the three and the longest carrying section. The ascent follows a path that is part paved, part boggy, and relentlessly steep in places. You carry the bike for a sustained period — 15-20 minutes for fast riders, 25-35 minutes for the rest. The summit ridge is exposed to whatever weather Yorkshire is serving, and in late September that can mean driving rain, fog, or wind strong enough to unbalance you with a bike on your shoulder. The descent is rough, wet, and unforgiving.
Pen-y-ghent (694m). The final peak. By this point you have been racing for 2-4 hours, your shoulder is bruised, your legs are heavy from running, and you still have to carry the bike up a rocky ascent with a short scrambling section near the top. The descent is the reward — fast, technical, and if you have any CX handling left in the legs, exhilarating. Then it is road and track back to the finish.
Between the peaks, the route uses a mix of tarmac roads, farm tracks, bridleways, and open fell. The road sections are where strong cyclists can make up time, but they are not long enough to dominate — a rider with 4.0 W/kg who walks the carrying sections will be beaten by a rider with 3.0 W/kg who runs them.
The weather. Late September in the Yorkshire Dales is not summer. Average high temperatures sit around 12-14°C at valley level, dropping to 5-7°C on the summits with wind chill. Rain is frequent. Fog is possible. The ground is wet — always — and the limestone is slippery when wet, which it always is. You are dressing for conditions that could range from cool and dry to near-winter in the space of a single ascent. Riders who pack for a mild autumn day and discover 5°C horizontal rain on Whernside summit lose time, body temperature, and composure.
The Physical Bar: Fitness Targets
The Three Peaks is not a W/kg event. It is not a VO2max event. It is a multi-discipline event that rewards adequate fitness across four domains, rather than excellence in one.
Cycling fitness. An FTP of 3.0 W/kg or above is enough to ride the road and track sections without losing significant time. Higher is better, but the returns diminish fast — the difference between 3.0 and 3.5 W/kg might be 3-4 minutes over the road sections, while the difference between running and walking the carrying sections is 10-15 minutes. Use the W/kg calculator for your current number, but do not fixate on it.
Running fitness. You need to run uphill on rough terrain while fatigued. A 10km trail run in under 55 minutes is a reasonable baseline. You do not need to be fast on the flat — this is not road running. You need to be able to sustain a purposeful hike-run on 25-35% gradients without blowing up. Hill reps on steep grass are the specific session. If you cannot currently run 5km without stopping, start the running programme 16 weeks out, not 12.
Carrying endurance. This is the one that catches people. Carrying a 9-10kg bike on your shoulder while climbing steep, uneven terrain for 15-25 minutes is a specific physical skill. It loads the shoulder, the core, the hip flexors, and the calves in a pattern that cycling never touches. Your heart rate will sit in Zone 4-5 during carrying sections regardless of how fit you are — the combination of upper-body isometric load plus running uphill plus altitude is metabolically expensive.
CX bike handling. The descents are rough, wet, and off-camber. If you cannot ride confidently on wet grass, through ruts, over rocks, and on off-camber slopes with a cyclocross bike, you will walk descents that other riders are riding — and that is where the mid-pack separates from the back third.
The 12-Week Framework
Three blocks of four weeks each, structured around the specific demands of the event. This is not a standard cycling periodisation — running appears from week one, carrying practice from week five, and the final block integrates everything into race-specific simulation.
Weeks 1-4: Base + Running
Volume: 8-10 hours/week cycling, plus 3 runs per week.
Cycling. Four to five rides, mostly in Zone 2. One weekend ride of 2.5-3 hours on mixed terrain — gravel, bridleways, farm tracks. If you have a CX bike, ride it. If you have been riding road all summer, now is the time to get off the tarmac and onto surfaces that bounce you around.
Running. Three runs per week, starting conservative. Your cardiovascular system is probably ahead of your connective tissue if you are coming from a cycling base — the aerobic engine transfers, but the tendons, ligaments, and bones do not. Week 1: 15-minute run, 20-minute run, 25-minute run, all easy pace on soft ground (grass, trails, not pavement). Build by no more than 10% per week. By week 4 you should be running 25-30-35 minutes across three sessions.
At least one run per week should include hills. Not flat road running — find a steep grassy slope and do 4-6 repeats of 2-3 minutes uphill at a hard but sustainable effort, walking back down. This is the specific movement pattern you will use on race day.
Strength. Two sessions per week of bodyweight and core work. Planks, side planks, press-ups, lunges, step-ups, single-leg calf raises. The core work is not optional — carrying a bike on one shoulder for 20 minutes with a weak core means a sore back and compensatory movement that costs speed. No gym required. A living room floor and a staircase are enough.
Weeks 5-8: Build + Carrying
Volume: 9-12 hours/week cycling, plus 3 runs and carrying practice.
Cycling. One quality session per week — sweet spot intervals at 88-93% FTP, starting with 3x10 minutes and building to 3x15 minutes by week 8. One longer weekend ride of 3-4 hours on mixed terrain. Include at least one technical CX skills session per week — practise dismounts, remounts, shouldering the bike, riding wet grass, riding off-camber slopes, braking on mud.
Running. Three runs, building to 30-35-40 minutes. One run is hill repeats — extend to 6-8 reps of 3 minutes. One run is steady trail running at conversational pace. One run is a shorter, faster effort with some tempo sections. By week 8, you should be comfortable with a 40-minute trail run on undulating terrain without walking breaks.
Carrying practice. This is where the programme diverges from any standard training plan. Once per week, shoulder your bike and walk/run uphill for 10 minutes in week 5, building to 20 minutes by week 8. Find the steepest grass slope near you — a local park, a golf course hill, a bridleway climb — and carry the bike up it repeatedly. Alternate shoulders every 5 minutes. If you only carry on one shoulder, the bruising and muscle imbalance will catch you by week 8.
The first time you carry a bike uphill for 10 minutes, two things will happen. First, your shoulder will hurt more than you expected. Second, your heart rate will spike harder than any interval session on the bike. This is normal. This is also why you start at 10 minutes, not 25.
Strength. Continue the core and bodyweight work. Add farmer's carries with a kettlebell or heavy bag — 3 sets of 60-second walks, building grip and shoulder stability under load. Walking lunges on grass. Single-leg step-ups onto a bench or low wall. These are not gym sessions — they are functional patterns that directly transfer to the carrying and running demands of the event.
Weeks 9-12: Specific + Taper
Volume: 10-12 hours/week in weeks 9-10, dropping from week 11.
Weeks 9-10: Race simulation. The weekend ride becomes a Three Peaks simulation. Ride 2-3 hours on mixed terrain, and at each significant climb, dismount, shoulder the bike, and carry it to the top. Then remount and ride the descent with full CX intent — wet grass, ruts, rocks, whatever your local terrain offers. Include 3-4 carry sections of 10-15 minutes within the ride.
If you can get to the Yorkshire Dales for a pre-ride, do it. Even riding one of the three peaks in training — the approach, the carry, the descent — gives you information that no amount of local simulation replicates. The limestone is different. The gradient profiles are specific. The boggy sections are in particular places. One pre-ride is worth five local simulations.
Running continues at three sessions per week. Hill repeats extend to 8-10 reps. Trail runs hold at 40-45 minutes. One run per week should finish with a 10-minute bike carry to practise the transition from running to carrying on tired legs.
Weeks 11-12: Taper. Volume drops 30% in week 11 and another 40% in week 12. Keep two short, sharp sessions — one CX skills session, one set of 4x3-minute efforts at VO2max on the bike. Run twice, shorter and easier. One 10-minute carry to keep the movement pattern loaded without fatiguing the shoulder. The fitness is in. The taper is about arriving at the start line with fresh legs, a conditioned shoulder, and the confidence that comes from having done the specific work.
The Carrying Problem
Bike carrying deserves its own section because it is the single most underprepared skill at the Three Peaks. Riders train their FTP for months. They might run a few times. Almost nobody practises carrying a bike uphill until the week before the race, and then they are surprised when their shoulder is purple and their back seizes up on Whernside.
Technique. Shoulder the bike by gripping the down tube with one hand and the opposite side of the handlebars with the other. The top tube sits across the back of your shoulder, with the saddle behind you and the bars in front. Your head goes through the frame triangle. The bike should sit stable without you gripping it hard — if you are death-gripping the down tube, the bike is poorly balanced and your forearm will cramp within five minutes.
Alternate shoulders every 5-8 minutes. Most riders have a dominant carrying side, but the weaker side needs conditioning too — if you only carry on the right shoulder for 25 minutes on Whernside, the muscle soreness and skin bruising will compromise your riding on Pen-y-ghent.
Weight matters. Every kilogram you carry up a fell costs energy and shoulder fatigue. A 7.5kg CX bike is noticeably easier to carry for 20 minutes than a 10kg gravel bike with accessories. Strip the bike to essentials. Remove bottle cages if you can carry bottles in pockets. Remove saddlebags. Anything removable that adds weight is a direct tax on your carrying sections.
Shoulder conditioning. The skin and muscle on top of your shoulder need exposure to the load. Start with 10-minute carries 12 weeks out and build gradually. Wear a thin base layer or jersey that you will race in — do not carry bare-shouldered and then discover that your jersey seam sits under the top tube and creates a pressure point. Some riders tape their shoulder on race day. Others wear a thin pad. The best solution is conditioning over weeks, not a race-day patch.
Practice on real terrain. Carrying a bike on a flat path is nothing like carrying it up a 30% wet grass slope. The bike swings, your foot placement becomes critical because you are looking down at uneven ground rather than ahead, and the gradient loads your calves and hip flexors in a way that flat carrying never touches. Find the steepest, roughest slope available and carry on it weekly.
Nutrition Strategy
The Three Peaks is not a long event by ultra-endurance standards — most finishers are done in 3-5 hours. But the intensity is relentless. There is no steady Zone 2 riding for an hour where you can comfortably eat a bar and drink a bottle. The road sections are raced. The carrying sections spike your heart rate into Zone 4-5. The descents demand full concentration. Finding time to eat and drink is a genuine tactical problem.
Pre-race. Eat a normal pre-race breakfast 2.5-3 hours before the start. Porridge, toast, a banana, coffee. Nothing exotic. 80-100g of carbohydrate. If you have gut-trained for higher carb intake, a small rice cake 30 minutes before the start is fine.
During. Target 60-80g of carbs per hour. Gels and liquid carbohydrate are easier to take during carrying sections than solid food — you can rip open a gel while hiking without breaking stride. Carry two bottles with carb mix on the bike and 2-3 gels in jersey pockets. Drink on the road sections where the intensity is more controllable.
The mistake most riders make is not eating in the first hour because they feel fine, then bonking on Whernside when the accumulated carb deficit hits them during the hardest carrying section. Start fuelling from 20 minutes in. Use the calorie calculator to estimate your total expenditure, but for a 3.5-5 hour race at this intensity, you are burning 600-900 kcal/hour and replacing a fraction of that — which is fine for the duration, as long as you start early and stay consistent.
Hydration. 500-750ml per hour depending on conditions. Two 500ml bottles on the bike is typically enough if you start fully hydrated. In warmer conditions — which occasionally happen in late September — a third bottle or a hydration bladder in a jersey pocket adds insurance. Electrolyte mix in at least one bottle.
Post-race. You will feel worse than you expect for the effort duration. The combination of running impact, carrying load, and high-intensity cycling fatigues muscles that a pure cycling event leaves untouched. Recovery drink or protein shake within 30 minutes, proper meal within 2 hours, and accept that your shoulders, calves, and hip flexors will be sore for 3-4 days regardless of what you do.
Common Mistakes
Training as a pure cyclist. The single most common mistake. Riders with an FTP of 4.0 W/kg who have never run uphill carrying a bike finish behind riders with an FTP of 3.0 W/kg who spent 12 weeks conditioning for carrying and running. The event rewards the athlete, not the cyclist.
No running preparation. Your cardiovascular fitness from cycling transfers. Your tendons, ankles, and impact tolerance do not. Riders who start running two weeks before the event get injured or finish with such sore legs that the final peak is a survival march. Running needs to start 12 weeks out, building conservatively.
Wrong shoes. Road cycling shoes with hard soles and recessed cleats are dangerous on wet limestone and steep grass. You will slip, you will lose time, and you may injure yourself on the descents. CX-specific shoes with aggressive tread patterns and SPD-compatible soles are the minimum. Test them on wet grass before race day.
Wrong bike weight. Riding a gravel bike with mudguards, a frame bag, two bottle cages, and a saddle pack adds 2-3kg that you carry up three mountains. Strip the bike. Every 500g removed from the bike is felt across 40-50 minutes of carrying. Some riders go as far as single-ring drivetrains, lightweight tubulars, and minimal bar tape to shave grams. At this event, weight savings are not marginal — they are directly proportional to shoulder fatigue and carrying speed.
Ignoring the descents. The carrying sections get all the attention, but the technical descents are where the mid-pack separates from the back third. Riders who walk rocky, wet descents because they lack CX handling skills lose 5-10 minutes across the race. Practise riding wet grass, off-camber slopes, and rocky drops on a CX bike every week during the build.
Underestimating the weather. Late September Yorkshire is not summer. Riders who start in a short-sleeve jersey and shorts, then hit 5°C horizontal rain on Whernside summit, lose body temperature and fine motor control. A lightweight gilet, arm warmers, and a waterproof shell that fits in a jersey pocket weigh almost nothing and prevent a 20-minute catastrophe on an exposed summit.
Kit, Gearing, and Logistics
Bike. A cyclocross bike, as light as possible. Carbon frame if budget allows. Drop bars. Disc brakes or cantilevers — disc brakes are better in wet conditions and the Three Peaks is always wet. Single chainring (36-40T) with a wide-range cassette (11-34 or 11-36). You do not need a front derailleur, and removing it saves weight and mechanical complexity. If you ride a gravel bike, that works too — but strip anything non-essential.
Tyres. 33mm tubulars for the serious racer; 33mm tubeless for everyone else. A CX-specific tread pattern with decent mud clearance. Do not run file tread — you need grip on wet grass, mud, and limestone. Pressure at 28-32 psi for tubeless depending on your weight, lower if conditions are particularly muddy. Carry a spare tube and a CO2 canister. There is no race support on the fell sides.
Shoes. CX-specific SPD shoes with aggressive tread. The tread pattern matters — you need grip on wet rock and steep grass, not just on the pedal. Shimano XC shoes, Giro Cylinder-style shoes, or any MTB/CX shoe with deep lugs and a walkable sole. Test them on wet grass at speed before race day. If you cannot run confidently in them on a steep, wet slope, they are the wrong shoes.
Clothing. Base layer (merino or synthetic, not cotton). Short-sleeve or long-sleeve jersey depending on forecast. Bib shorts — consider ones with minimal padding, since you are running in them too and thick pads chafe when running. Arm warmers. A packable waterproof shell (Gabba-style or ultralight rain jacket) in a rear pocket. Lightweight gloves — your hands will get cold and wet on the descents, and cold hands mean poor braking. Cycling cap under helmet for rain.
Gearing. 1x drivetrains are standard. A 36T or 38T ring with an 11-34 or 11-36 cassette covers the road sections comfortably and gives you a low enough gear for the rideable approaches to the carries. You will not be riding at high speed for long enough to miss a 50T chainring. If running a 2x setup, a 36/46 with an 11-28 cassette works but adds weight and complexity. Simpler is better when you are shouldering the bike repeatedly.
Logistics. The event is based in Helwith Bridge, near Horton-in-Ribblesdale. Accommodation in the Dales books up early — sort it as soon as your entry is confirmed. Arrive the day before. Reconnaissance of the first carrying section on Ingleborough is worthwhile if you have not raced before. Registration is typically on the morning. Carry your own nutrition — there are no feed stations on the course. A small emergency kit in a jersey pocket (phone, £20 note, mini first-aid) is sensible given the remote terrain.
Free Plan Templates (Inside the Community)
Inside the Roadman Cycling community on Skool we host a library of plan templates covering base, build, VO2max, FTP, and event-specific blocks. For Three Peaks, the crossover training templates — cycling plus running plus strength — are the starting point. Same structural approach we use as the foundation for paid coaching. The community also has riders who have raced the event and can share real-world carrying and kit advice. Free to join.
If you want to understand how running and cycling fitness interact — the VO2max crossover, heart rate zone differences between sports, and how to manage total training load when doing both — the Running and Cycling Crossover Guide covers the physiology in detail.
How Roadman Coaches This
Three Peaks preparation is different from anything else we coach. It is not a cycling plan with running bolted on. It is a genuine multi-discipline build where the running, carrying, and CX skills need their own periodisation alongside the cycling volume.
At Roadman Cycling we structure the 12-week build around your current running baseline, your carrying tolerance, your local terrain, and how much time you have to train across multiple disciplines in a single week. Most amateur riders have 8-12 hours a week. Fitting cycling, running, carrying practice, strength work, and CX skills into that window without overtraining requires careful load management — not just more hours.
Our coached athletes work through TrainingPeaks with structured workouts, daily metrics, and a coach who reads your data and adjusts the balance between cycling and running load week by week. Coaching starts at $195/month. Learn more about our coaching or how we work with riders across the UK and Ireland.
The Three Peaks is one of the last truly unique events in British cycling. No timing chips on a road circuit. No feed stations. No course marshals on the fell tops. Just you, a bike, three mountains, and whatever the Yorkshire Dales decides to throw at you in late September. Train the carrying. Train the running. Respect the weather. The rest is between you and the fells.
