The 2027 course
Everything starts from the Union nautique, on the shore of Lake Gérardmer. The swim is in the lake, in a single wave, on a course marked by yellow buoys. The Olympic bike course is three 13.3 km laps including the Rayée climb (a 15% section), 330 m of climbing per lap. The XL rides three 31 km laps in the Ballons des Vosges nature park, fast but with nine climbs, 630 m of climbing per lap. On foot, the Olympic runs two 5.5 km laps along the lake and the XL three 7 km laps around it, shaded and rolling in their first half, flat afterwards. All bike courses are closed to traffic.
What the race asks of your training
Short, steep climbs on the bike
The Rayée climb reaches 15% and comes back on every lap of the Olympic distance. Hill sessions on the bike, seated then standing, and one long weekly ride on hilly roads prepare you better than flat volume. The sample plan below is for a flat Olympic distance: remember to add these climbs.
No drafting
Drafting is banned on every race and aero bars are allowed: everyone rides alone at their own pace. Threshold sessions on a turbo trainer or on the road, with no wheel to follow, match the race effort exactly.
Running after the climbs
The run follows the lake on a shaded, rolling loop, 80% on tarmac. Linking bike and run once a week late in the build-up gets your legs used to running after the climbs.
A build-up through the summer
For a race in early September, the key weeks fall in July and August. The Olympic distance starts at 1:30 pm: doing a few bricks in the early afternoon, testing your lunch, prepares you for the time of day and the heat on race day.
The plan below prepares the Distance olympique format, for an athlete at intermediate level with 5 days available per week, with race day on 5 September 2027. Aiming for another format?

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.

- How do you get a bib now that it is sold out?
- Pre-registered athletes without a place are on the waiting list: a second wave of places goes out on 26 October 2026, then draws take place all year from 29 October. There is also the official resale on Njuko, open until 19 August 2027, and charity bibs with Mécénat Chirurgie Cardiaque, in exchange for fundraising.
- How much is the entry fee?
- In 2027: XL €225 with a triathlon licence, €240 without; Olympic distance €110 or €120; Discovery €55 or €61. Without a licence, a medical certificate less than a year old is required.
- Is a wetsuit allowed?
- Yes, as long as the water is below 24.6 °C. The organisers announce the temperature in race week.
- Triathlon de Gérardmer: how many weeks of preparation?
- For an athlete at intermediate level, Endu builds a 15-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: 19 of 19 checks passed. A 15-week build (recommended minimum: 8); a longest run never more than 8% above the previous month’s; 83% of the time at easy effort; a taper cutting volume by 66% in race week. The rules and their sources are public on endu.fr/en/controle-technique.
- How many sessions per week?
- This example has 5 sessions per week. You choose 4 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.
