AI quick summary
- A criterium is a closed-circuit race on a short loop (0.5–2 km), 30–60 minutes duration, with corners every 200–500 meters. The pace is relentless: 40+ km/h average, with surges to 50+ km/h out of every corner. It's the most accessible entry into bike racing
- The accordion effect: the rider at the front exits the corner at full speed; the rider at the back has to brake, then sprint to close the gap. In a 50-rider field over 60 minutes, the back-row rider does 100+ micro-sprints. This is why being near the front saves enormous energy
- Tactics: position before corners (front 10 riders don't brake; back 10 riders sprint out of every corner), conserve energy mid-race (don't chase every attack), and save your sprint for the final lap. Most crits end in a field sprint
- Fitness: crits require threshold power (the ability to sustain 90%+ FTP for an hour) and repeatability (the ability to surge to 150% FTP, recover in 10 seconds, and do it again 40 times). This is called 'anaerobic capacity' or 'repeatability'

What makes crits unique
A criterium compresses all of road racing into a tight, fast package: a short circuit (typically a city block or a business park loop), raced for a set time (30 minutes for beginners, 60+ for pros), with a prime lap (a sprint for a prize mid-race) and a field-sprint finish. The corners — typically 4–8 per lap — are the defining feature: the race never stops accelerating.
The accordion effect: picture a spring. When the front rider enters a corner, they brake, coast through, and accelerate out. The rider behind them does the same, slightly delayed. By the time this wave reaches the back of the field (10–20 riders back), the front is already at full speed — and the back-row rider has to brake harder (losing more speed) and sprint harder (closing a bigger gap). Over 60 minutes with a corner every 20 seconds, the back-row rider does hundreds of micro-sprints. The front-row rider rides smoothly. Position is everything.

Race tactics
Crit racing tactics by race phase.
| Phase | What happens | What to do |
|---|---|---|
| First 10 min | Fast and chaotic; field sorts itself | Hold position near front 15; don't chase early attacks |
| Mid-race | Attacks and primes; field settles into rhythm | Sit in top 20; let other teams chase; conserve |
| Last 10 min | Position wars; the sprint trains form | Fight for top 10 position; never lose wheels |
| Final lap | Lead-out trains; field sprint or breakaway | Follow your sprinter's wheel; sprint at 200m |

Training for crits
Crits demand two specific fitness qualities: (1) Threshold — the ability to sustain near-FTP for an hour. A crit is essentially a 60-minute time trial with surges. Your FTP is the floor. (2) Repeatability — the ability to surge to 150%+ FTP, recover in 5–15 seconds, and repeat dozens of times. This is the skill that lets you follow attacks and exit corners without getting dropped.
The training: threshold work (3×10 min at FTP, weekly) raises the floor. Anaerobic repeat work (10×30 sec at 150% FTP with 30 sec recovery, weekly) builds the ceiling. And motorpace sessions (drafting behind a scooter at 50 km/h) simulate the speed and acc/decel pattern of a crit. If you can sustain FTP for 60 minutes and repeat 30-second surges without fading, you can finish a Cat 4 crit.

Survival skills
Cornering: the single most important skill in a crit. A rider who exits corners smoothly (no unnecessary braking, carrying speed through) saves enormous energy vs a rider who brakes and sprints out of every corner. Practice cornering on a closed circuit: find a parking lot, set up a figure-8, and practice carrying speed through the turns at progressively higher speeds.
Positioning: fight for the front 10–15 positions in the first 5 minutes. Once you're there, it's easier to stay (the front rides smoothly; the back is chaos). If you drift back, getting forward again costs 5× the energy of staying there. Hold your wheel — if a gap opens in front of you, close it immediately. Gaps only grow.
Crashes: crits have more crashes than any other race format (tight corners, high speed, close proximity). Minimize your risk: stay near the front (most crashes happen mid-pack, where the accordion is worst), hold your line through corners (don't dive-bomb the inside), and if a crash happens ahead, aim for the gap, not the brakes — you can often thread through if you don't panic.
