The 2026 course
The L starts with a rolling start at 7 am from the beach of Lake Maubuisson, in Carcans: one 1,900 m swim loop, in water expected at 18-20 °C. Bike: a single 90 km loop through Maubuisson, Hourtin-Plage, Naujac-sur-Mer, Saint-Laurent-Médoc and Carcans, on good roads, open to traffic, 194 m of climbing. Run: two out-and-backs between the beachfront paths of Maubuisson and the cycle paths of the Bombannes forest, 21 km and 91 m of climbing.
What the race asks of your training
A flat bike, on the aero bars
194 m of climbing over 90 km, non-drafting: you stay in the aero position almost the whole way. Long rides at a steady pace, with 20 to 40-minute blocks at target pace on the aero bars, prepare you better than hills. Roads stay open to traffic, with marshals.
A fast half marathon
Two out-and-backs between Maubuisson beach and the cycle paths of the Bombannes forest, with 91 m of climbing. Bricks of riding followed by 20 to 40 minutes at half-marathon pace, on flat ground, teach you to run fast straight off the bike.
An early-May race
For 7 May, a 16-week build-up starts in mid-January: most of the bike volume is done in winter. The organisers expect water at 18-20 °C and recommend a wetsuit; one or two open-water swims in April help you get used to cool water.
Generous cut-offs
2h10 to leave the water, 5h30 to rack the bike and 8 hours to finish. For a first half, the challenge is less the cut-off than pacing a flat bike leg where people often start too fast.

Why this plan works
Science-based periodisation
Base → build → specific → taper, with a recovery week every 3 to 4 weeks. Load goes up, but never two hard weeks in a row without a breather.
Paces, not vague feelings
Every session has target zones (pace, HR) computed from your MAS or a reference performance. A MAS test is built into the plan if you don't know yours.
Three disciplines, one load
Swim, bike and run are planned together: brick sessions, key sessions spread out, and a coherent total load week after week.
A plan that listens
After each session you rate how it felt (RPE). Too hard? The plan eases what follows. Skipped a session? It reschedules or absorbs it.
On your watch
On Garmin with the Endu app, on COROS by direct sync: the guided workout shows up on your wrist, step by step.

- When does registration for the 2027 Frenchman open?
- They have been open since June 2026, on Klikego. As of 17 October 2026, the L, the M and the XS are sold out; the XXL and the Challenge remain open until 15 April 2027. The children’s races open in January 2027.
- Is drafting allowed?
- No on the L and the XXL (12 m between bikes, a 5-minute penalty per blue card) and on the M (7 m). Only the XS is draft-legal.
- What are the L cut-offs?
- 2h10 for the swim, 5h30 at the end of the bike and 8 hours to finish.
- Frenchman Triathlon: how many weeks of preparation?
- For an athlete at intermediate level, Endu builds a 21-week preparation. If your race is closer, the plan compresses phases while keeping the taper; if it's further away, it lengthens the preparation, and when the gap is large the preparation starts right away, gently and at your current volume, before building up.
- Is this plan well built?
- Pass at Endu’s plan check, the same as for any plan: 21 of 21 checks passed. A 21-week build (recommended minimum: 12); a longest run never more than 6% above the previous month’s; volume rising at most 13% from one week to the next; 82% of the time at easy effort; the longest session 3 weeks before the race; a taper cutting volume by 77% in race week. The rules and their sources are public on endu.fr/en/controle-technique.
- How many sessions per week?
- This example has 6 sessions per week. You choose 5 to 7 training days and the exact days (e.g. Tue, Thu, Sat, Sun): the plan sticks to them.
- I'm a beginner, is this plan for me?
- The plan adapts to your declared level (beginner to semi-pro): starting volume, progression and intensity change. Endu also offers a "Discovery" mode without a race to build a base first.
- Can I follow sessions on my watch?
- Yes, on Garmin and COROS. On Garmin, the Endu app (Connect IQ Store) shows today’s session and starts it as a guided workout. On COROS, link your account from your profile: your running, trail and cycling sessions land in the watch calendar. Other brands are not supported yet.
- How much does it cost?
- 14-day free trial, then €7.99/month with no commitment or €59.88/year (€4.99/month). Unlimited objectives and sports.
