24 Heures Vélo at Le Mans: Course, Route Profile & Map
At the 24 Heures Vélo in Le Mans the Bugatti circuit belongs to cyclists for a whole weekend: from Saturday 3 pm to Sunday 3 pm, the winner is whoever completes the most laps of the 4.2-kilometre course – solo or as a relay team. The track is wide, safe and never steep; the real opponent is the clock.
Course & Elevation
Every late summer the 24 Heures Vélo brings around 3,000 riders from some 15 countries onto the Le Mans motor-racing venue, with the 17th edition set for 2026. The race runs on the 4.2-kilometre Circuit Bugatti – the same tarmac used by the 24-hour car and motorbike races. You start solo or in teams of two, four, six or eight, with exactly one rider on track at any time.
The lap itself is short and rhythmical: from the start-finish area at around 56 metres the track climbs straight away in a near-500-metre drag at three to five percent to its high point just above 80 metres, then rolls gently up and down back to the lowest point – 46 metres of gain per lap without a single steep section. A good third of every lap points downhill; the rest splits between flat sections and shallow ramps.
On a wide, closed circuit with no traffic, groups form quickly, and over 24 hours drafting is worth whole laps. At night the race gets quieter and colder, but the track stays the same: a course that hides nothing, yet exposes every lapse in discipline over the distance.
Pacing Strategy
Pace a time window here, not a distance. Solo, that means an intensity well below threshold that still feels controllable after six hours, plus disciplined hourly fuelling – the course never forces a break, so you have to schedule it yourself. In a team the character flips: depending on team size you ride short, hard turns near threshold with incomplete recovery in between; fix your changeover schedule in advance and hold it through the night.
The lap sets the rhythm: the only climb worth the name comes right after start-finish – close to 500 metres at three to five percent. This is where groups split and where you decide whether you keep the wheel. Invest here in a controlled way, because a group held on the drag pays back several times over on the descending remainder of the lap.
The classic trap is the first hour: after the 3 pm start the circuit feels fast and every passing group is an invitation. Accept them all and you pay between 3 and 6 am – which is where this race is actually decided.
Training plan for 24 Heures Vélo at Le Mans: 12-week build
How you train for the 24 Heures Vélo depends on your format. Solo, it is a pure endurance race: many hours just below your steady-state ceiling, interrupted only by the lap's short ramps. As a relay team it becomes a 24-hour interval race – repeated turns of roughly 30 to 60 minutes at high intensity, with breaks that never allow full recovery.
For solo riders durability is everything: long endurance rides of four to six hours, ideally in a group, because drafting on a fast circuit is a skill worth practising. Add sessions where you produce race pace again after several hours of riding, and rehearse hourly fuelling until it runs on autopilot.
For teams the opposite of an even preparation applies: train repeated threshold efforts – blocks of 20 to 40 minutes with incomplete recovery, including two or three in a single day. The near-500-metre drag after start-finish also demands short uphill accelerations out of a group. Both formats share two remaining fronts: the night and the head. Schedule some rides at dusk or in the dark with lights, and simulate at least one race day on a disrupted sleep rhythm. With a date in late August, it is also worth building deliberate heat exposure into summer training.

| KM 0.6 | 0.5 km | 3.2% | 5.2% | +14m | — |
Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
