September rolls around and there is a very specific feeling that every road cyclist knows. The season is done. The target event has been and gone. The evenings are getting shorter, the mornings are getting colder, and there is a turbo trainer in the garage that you have been pretending does not exist since April. You know what is coming. Four months of staring at a screen, pedalling to nowhere, watching your motivation slowly dissolve into the carpet beneath the sweat puddle.
Here is the thing nobody tells you: there is an entire racing season that starts precisely when your road season ends. It runs from September through February. The races last under an hour. You can enter on the day for $15-25. You will get muddier than you have been since you were eight years old. And you will have more fun on a bike than you have had all year.
That is cyclocross. And if you have never tried it, this autumn is the time.
Picture this: a park on a Saturday afternoon in November. Taped-off course through trees, across a football pitch, up a muddy bank, over two wooden barriers, through a sandpit, and back around for another lap. Forty riders on the start line. A whistle blows. For the next 45 minutes, you ride as hard as you can, jump off the bike, run with it on your shoulder, jump back on, slide through a corner, and do it all again. Your mates are standing at the top of the hill with a cup of coffee, heckling you every time you come past. You finish, covered in mud, lungs burning, laughing. The whole thing costs less than a decent pub lunch.
That is CX. And once you try it, October through February will never look the same again.
What Exactly Is Cyclocross?
Cyclocross is short-course, off-road bike racing on a circuit typically 2.5 to 3.5 kilometres long. Races are timed rather than distance-based — elite races run for 60 minutes, amateur categories usually 40 to 50 minutes. You ride as many laps as you can in that window. The commissaire sets the lap count after the first lap based on the leader's time, so everybody knows how many laps remain.
The courses are designed to include obstacles. Barriers — wooden planks 40cm high that you cannot bunny-hop at speed — force you to dismount, shoulder the bike, run over them, and remount. Muddy run-ups too steep to ride mean shouldering the bike and running. Sand pits, off-camber turns on wet grass, tight switchbacks through trees, stairs. The course designer's job is to make sure you cannot simply ride the whole thing. You will get off the bike. You will run. You will get dirty.
The sport originated in Europe in the early 1900s — road cyclists in France and Belgium started racing across fields and through forests during winter to maintain fitness. It became a formalised sport in the 1950s and by the 1990s Belgium and the Netherlands had turned it into something approaching a national obsession, with tens of thousands of spectators lining courses, cowbells ringing, frites vans doing roaring trade, and beer flowing freely at 10am on a Sunday.
Here is where it gets really interesting for road cyclists: cyclocross is essentially a 40-60 minute interval session with barriers, mud, and an audience. Your aerobic engine — the one you have spent all summer building — transfers directly. The intensity sits right around VO2max for most of the race, with short anaerobic bursts for starts, run-ups, and surges. If you have decent road fitness, you already have the engine. What you lack are the skills. And that gap is what makes it exciting — you actually have something new to learn.
The atmosphere at a CX race is unlike any other cycling event. Road races and time trials are spread across miles of road and spectators see you twice if they are lucky. CX courses are compact. Your family, your mates, your club can stand at one spot and see you every four minutes. They can heckle you on the run-up, cheer you through the barriers, and laugh at you when you slide out on that off-camber corner for the third time. It is participatory spectating. People bring camping chairs and flasks and make an afternoon of it. The post-race scene — everyone muddy, comparing war stories, eating cake — is the most sociable thing in cycling.
Equipment: What You Actually Need
Let me break this down honestly, because the internet will tell you that you need a dedicated CX bike with cantilever brakes and a 46/36 crankset and exactly 33mm tubular tyres at 1.8 bar. You do not. Not for your first season.
The bike. A dedicated cyclocross bike is the ideal tool. It has aggressive geometry — short chainstays for quick handling, a high bottom bracket for pedal clearance over ruts, and tyre clearance for 33mm rubber. But if you already have a gravel bike, you are 90% of the way there. Swap the tyres for something treaded in the 33-38mm range, drop the pressure, and race. The differences between a gravel bike and a CX bike — slightly longer chainstays, slightly lower bottom bracket, slightly more relaxed geometry — are real, but they matter at the sharp end of an elite race, not in your first season.
Can you race on a road bike? Technically, some races allow it. Practically, do not. Road tyre clearance means 28mm maximum, which is not enough grip on mud or grass. The bottom bracket is too low and you will strike pedals. Road gearing is wrong. And if you crash — you will crash — carbon road frames and tarmac-focussed components do not mix well with mud, barriers, and being dropped on the ground repeatedly.
Tyres. This is the single most important equipment choice. You want a treaded CX tyre, 33mm for pure CX bikes or up to 38mm if your frame allows. For mixed conditions — the most common scenario in the UK — a file tread with small knobs works well. For proper mud, go for something with pronounced knobs and spacing. Brands like Schwalbe, Challenge, Vittoria, and Donnelly all make excellent CX tyres. Run them at low pressure: 1.8 to 2.2 bar for tubeless, slightly higher for clinchers with tubes. If you are running tubes, carry on, but know that pinch flats at CX pressures are a real risk. Tubeless is worth the setup hassle.
Gearing. Most CX bikes run a single chainring — 1x — with a 38-40t ring up front and an 11-36 cassette at the back. This is ideal. You do not need a big ring because CX courses rarely have long flat sections where you would use it, and a single ring means no front derailleur to get clogged with mud and no chain drop when you are bouncing over rough ground. If your gravel bike has 1x already, perfect. If it has 2x, that is fine too — just stay in the small ring most of the time.
Pedals. This is non-negotiable. You need SPD-style mountain bike pedals and shoes with treaded soles. Road pedals and road shoes are wrong for CX. Road cleats clog with mud immediately. Road shoes have smooth soles designed for walking from the car to the cafe — you cannot run in them. SPD cleats are recessed into the sole, they shed mud, and the shoes have tread for running, climbing stairs, and scrambling up muddy banks. If you own one pair of SPD shoes already, you are sorted. If you need to buy some, Shimano's XC range is excellent value.
Clothing. Less is more. A skinsuit is traditional and practical — no flapping fabric to catch on branches or barriers. But a regular jersey and bib shorts work perfectly well. Layer with arm warmers and a base layer as the temperature drops. Knee warmers for really cold days. Gloves always — wet bars, mud, and cold hands are a bad combination. Do not bother with overshoes. They will be shredded by mud and running within one lap. Your road helmet is fine. Some riders prefer an MTB helmet with a visor to keep mud and rain out of their eyes, which is practical if you have one.
Realistic minimum spend if you already have a gravel bike: a set of CX tyres ($60-100), SPD pedals if you do not have them ($50-80), SPD shoes ($80-150), and entry fees ($15-30 per race). That is it. Under $300 gets you racing.
The Skills That Matter
Here is where road converts struggle and experienced CX riders pull away. The fitness gap between a strong road rider and a CX regular is often small. The skills gap is enormous. The good news: every one of these skills is learnable in your garden.
Dismounting. This is the foundational CX skill. You are approaching a barrier or a run-up at speed and need to get off the bike smoothly without stopping. Here is the sequence:
- Unclip your right foot and swing your right leg over the saddle behind you, so both legs are on the left side of the bike.
- Your left foot is still clipped in. Your right foot is hovering behind your left leg.
- Step down with your right foot as you unclip your left foot.
- You are now running alongside the bike, right hand on the bars, left hand on the top tube or saddle.
That is it. The whole movement takes about two seconds when it is smooth. When it is not smooth, it takes about ten seconds and involves swearing. Practise it on grass. Twenty minutes in the garden, five sessions, and you will have it. The key is committing to the leg swing — hesitating is what causes the tangled-legs-handlebars-disaster that everyone does exactly once.
Remounting. The reverse. You are running alongside the bike after the barriers and need to get back on without stopping.
- Both hands on the bars. Running alongside on the left.
- Jump, swinging your right leg over the saddle.
- Land on your inner right thigh on the saddle — not directly on the saddle, because you need to avoid the, shall we say, sensitive landing.
- Slide forward into position and clip in.
This one takes slightly more practice and slightly more courage. The jump is the bit that feels unnatural. Start at walking pace, build up to jogging, then running. You will land badly a few times. That is normal. Do it on grass, not tarmac.
Barriers. The standard CX barrier is about 40cm high. The approach: dismount smoothly, shoulder the bike (right arm through the frame triangle, top tube on your right shoulder), step over the barriers, remount. Two barriers are typical, spaced a few metres apart. The fast riders never break stride — dismount, shoulder, step-step, drop the bike, remount, gone. In your first few races, just getting over them without falling over or dropping the bike is a victory.
Shouldering the bike. You need to carry your bike on your shoulder for run-ups, stairs, and barrier sections. The standard method: right arm reaches through the main triangle from the non-drive side, grab the left drop or the down tube, and rest the top tube on your right shoulder. The bike sits at about a 45-degree angle. It weighs roughly 8-9kg, which does not sound like much until you are running up a 20% gradient in the mud with it.
If you have never run with a bike on your shoulder, practise it before race day. It uses your traps, your core, your grip, and your legs in a way that pure cycling never trains. Start with five-minute carries and build from there. Your shoulder will bruise — everyone's does for the first few races. Some riders tape padding onto their right shoulder. Others just accept it.
Cornering on grass and mud. Forget everything you know about cornering on tarmac. Road cornering is about lean angle, tyre grip, and smooth arcs. CX cornering is about staying upright. Keep your weight low, outside foot down, inside foot up — same principle as the road, but exaggerated. Look where you want to go. Accept that the rear wheel is going to slide. Let it. Fighting the slide is what causes crashes. Smooth, controlled skids are part of the sport. You will get a feel for how much grip you have after a few laps. The first corner of the first lap is always the sketchiest because you have not read the conditions yet.
Running. Some sections of a CX course are faster on foot than on the bike. Muddy hills, deep sand, steep banks. The instinct for a road cyclist is to try to ride everything — to stay on the bike at all costs. Resist that instinct. Jumping off and running is often three to five seconds faster than grinding up a muddy slope at 4 km/h with the rear wheel spinning. Watch the fast riders. If they are running, you should be running.
Your First Race: What to Expect
You have practised mounting and dismounting in the garden. You have ridden your gravel bike on some muddy trails. You have entered a local league race. Now what?
Arrive early. An hour before your race. You need to register, pin a number on, and — this is important — ride a few practice laps of the course. Practice laps are your chance to learn the course: where the barriers are, which line to take through corners, where the run-up starts, how deep the mud is. Every CX race allows practice laps before the gun goes off. Use them. Riders who skip practice laps spend the first two race laps figuring out the course while everyone else is racing.
Gridding. CX races grid riders by ranking or category points. If you have none — and you will not, because this is your first race — you start at the back. That is fine. The start is chaotic regardless, and starting at the back means you have space to find your rhythm without being caught up in the first-corner pile-up.
The start. A CX start is violent. Thirty, forty, fifty riders sprinting into a course that narrows to single-track within 200 metres. Your heart rate will hit maximum within 90 seconds. This is normal. Do not panic. The first lap is always the hardest because you are fighting for position, you are nervous, and your body is in shock. Settle after the first lap. Find a sustainable rhythm. The race is 40-50 minutes — you cannot sprint the whole thing.
Race pace. Here is what shocks most road converts: CX intensity is relentless. There is no sitting in a group. There is no drafting. There are no easy flat sections where you recover. You are either pedalling hard, running, or trying not to crash. The closest road equivalent is a 20-minute FTP test, except it lasts twice as long and involves running and jumping over planks. Pace yourself. Go out at 90% rather than 100% and you will be overtaking people in the second half who went out too hard.
Getting lapped. It happens. In CX, if the leader catches you, you may be pulled from the race to keep the course clear. Do not take it personally. In many beginner categories, the commissaire is lenient about this. The goal for your first race is to finish, to learn, and to come back.
After the finish. Clean your bike. CX is brutal on equipment — mud in the drivetrain, water in the headset, grit everywhere. A bucket of warm water and a brush straight after the race prevents expensive problems later. Then eat cake, drink tea, compare mud lines with strangers, and start planning next weekend.
Training for CX as a Road Cyclist
The good news: most of your road fitness transfers directly to CX. Your aerobic base, your threshold power, your ability to suffer — all of it translates. You are not starting from zero. But there are gaps, and those gaps are what will limit you if you do not address them.
What transfers. Your VO2max and threshold fitness are the engine of CX racing. A strong road rider with an FTP of 3.5+ W/kg and good VO2max numbers has the aerobic capacity to be competitive in local CX races. The fitness demands are similar to a long interval session — sustained hard efforts with brief recovery — and your road training has built exactly that system.
What does not transfer. Three things: skills, running, and upper body conditioning. Skills we have covered — practise mounting, dismounting, and cornering every week. Running is the surprise. CX requires short, hard running efforts while carrying a bike. If you have not run in years, your legs, feet, and connective tissue are not ready for it. Start with two short runs per week — 15 to 20 minutes at an easy pace — six weeks before your first race. Build to 25-30 minutes. You do not need to be a runner; you need to be able to run for 30-second bursts without pulling a calf muscle.
Upper body conditioning matters more than road cyclists expect. Shouldering and carrying the bike loads your traps, shoulders, and core in ways that cycling never does. Two sessions per week of simple exercises — press-ups, plank variations, dumbbell rows, shoulder presses — will prepare those muscles for race demands. Nothing heavy, nothing complicated. Fifteen minutes twice a week.
CX-specific sessions. If you are training four to five days per week on the bike, replace one session with a CX-specific workout:
- Grass crits. Find a park. Set up a course using trees, paths, and natural features. Ride it for 30-40 minutes at race intensity. Include dismounts and remounts every lap even if there are no barriers. This is the single most useful CX training session you can do.
- 30/30 intervals. 30 seconds at maximum effort, 30 seconds recovery, repeated 10-15 times. Rest five minutes. Repeat. This mirrors the on-off intensity of CX racing — hard effort, brief recovery at a corner or barrier, hard effort again.
- Threshold with surges. 20 minutes at threshold with a 10-second sprint every two minutes. CX racing is not steady-state — it is threshold riding interrupted by constant accelerations out of corners, off barriers, and up short climbs.
Keep your long endurance rides. Keep one hard interval session. Add one CX-specific session and one skills session. That is a week of training that builds CX-specific fitness without abandoning the road base you have already built.
The UK and European Scene
CX racing in the UK and Ireland is thriving, and the barrier to entry is about as low as it gets in competitive cycling.
Local leagues. Most regions in the UK have a CX league that runs from September or October through to January or February. The London CX League, the Yorkshire CX Association, the North West CX League, the West Midlands CX League, the Scottish CX series — wherever you are, there is almost certainly a league within driving distance. Races are typically on Saturday or Sunday afternoons, last 40-50 minutes for amateur categories, and cost $15-30 to enter. Many allow entry on the day. You turn up, pay your money, pin a number on, and race.
National championships. British Cycling runs the National CX Championships in January, with categories from Under-12 to Veteran 60+. Cycling Ireland runs a national series too. These are the sharp end of domestic CX, but the age-group and category system means there is a race for everyone, from first-timers to elite riders.
The Belgian experience. If you want to see what CX looks like when an entire country cares about it, go to a Belgian World Cup round. Koksijde, Overijse, Namur — these are events with 30,000 to 40,000 spectators, temporary grandstands, live television, and an atmosphere that makes a Premier League football match look subdued. The course at Koksijde runs through beach sand dunes. Namur has a notorious descent called the Citadelle that is essentially a cliff with tape on either side. Watching Wout van Aert or Mathieu van der Poel race a muddy Belgian CX is one of the great spectacles in cycling. And here is the thing — on the same day, at the same course, amateur categories race the same circuit. You can race the same sand dunes the pros raced hours earlier. Try doing that at the Tour de France.
Finding races. British Cycling's event calendar lists most sanctioned CX races in the UK. The website is clunky but functional — search by discipline (cyclocross) and region. For unsanctioned or grassroots races, local league websites and Facebook groups are your best source. In Ireland, Cycling Ireland's event listings cover the national series. The CX community is small, friendly, and vocal online — ask in any cycling forum or local club group and someone will point you to the nearest races.
Why CX Makes You a Better Road Cyclist
This is the part that should interest every road cyclist reading this: a CX season does not just fill the winter months. It actively makes you faster on the road the following year.
VO2max development. CX racing sits right at VO2max intensity for most of the race duration. Eight to twelve weeks of weekly racing at this intensity is a VO2max training block that no coach could programme better — because it is fun, competitive, and self-paced. Dr Stephen Seiler, whose polarised training research has shaped how most of us think about training distribution, has noted that competitive racing is one of the most effective ways to develop top-end aerobic fitness because athletes will push harder in a race than they ever will in training. A CX season is essentially a structured VO2max block disguised as fun.
Bike handling. You know the moment when you hit a patch of gravel on a road descent and your stomach drops? CX fixes that. After a season of cornering on wet grass, riding through mud, sliding on off-camber slopes, and recovering from rear-wheel slides, your bike handling on tarmac feels absurdly secure. The road cyclist who has raced CX corners with more confidence, descends more smoothly, and reacts to unexpected surface changes without panicking. That confidence is not abstract — it is built through hundreds of small corrections on slippery surfaces that your reflexes learn and retain.
Anaerobic capacity. CX racing hammers your anaerobic system. Starts, surges, run-ups, barrier sections — they all demand short, maximal efforts followed by incomplete recovery. That is exactly the energy system that decides road races in the final kilometres, that lets you respond to attacks on climbs, and that separates the riders who can surge from the riders who can only sustain. A winter of CX racing builds that capacity in a way that turbo intervals cannot replicate, because the efforts are reactive, varied, and unpredictable.
Mental freshness. This might be the biggest benefit of all. Four months of turbo training in a dark garage kills motivation. Four months of CX racing, with mud and mates and cake and new skills, keeps you engaged and competitive through the winter. You arrive at the start of road season in March having raced every weekend, having trained hard, and — critically — still wanting to ride your bike. The rider who turboed all winter arrives fit but mentally cooked. The rider who raced CX arrives fit and hungry. That difference shows by May.
If you are looking for a community of cyclists who race, train, and have a laugh about it, that is exactly what the Skool community is for.
The fun factor. I have saved this for last because it sounds soft, but it matters. Cycling can become a grind. Power numbers, training load, TSS, recovery scores — the data-driven approach that makes us faster can also make the sport feel like a job. CX strips all of that away. You pin a number on, you race in the mud for 45 minutes, you laugh with your mates, you go home. There is no power meter strategy. There is no aero position. There is just riding your bike as fast as you can over stupid obstacles in the cold and the rain, and somehow enjoying every second of it.
That is the thing about cyclocross. It reminds you why you started cycling in the first place.
So here is my suggestion: find your local CX league, enter the first race, and see what happens. The worst case is you spend $20 and an afternoon getting muddy. The best case is you find a winter sport that makes you fitter, more skilled, and happier on the bike than anything else you have tried.
See you at the barriers.
