When is the 2027 Annecy triathlon?

The 2027 date is not announced yet: the official site says details will be released soon. The 2026 edition took place on Sunday 27 September, with the children’s and adapted-sport events on Saturday 26.

What distance is the Annecy triathlon?

An Olympic distance: a 1.5 km swim, 43 km bike with 770 m of climbing and a flat 10 km run. It is the only adult distance, solo or relay.

How much does the Annecy triathlon cost?

In 2026: €55 or €60 solo depending on licence status, plus €22 for the Licence Expérience for non-licensed athletes, and €90 per relay team. 2027 prices are not published.

Triathlon d'Annecy: 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.

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.

The 2026 course

Start and finish at the Pâquier, in Annecy. The 1.5 km swim is in the lake, with a passage under the Pont des Amours. The bike, 43 km and 770 m of climbing, rides through the Bauges regional nature park, with views of the lake. The 10 km run is flat, along the lakeshore and through the Pâquier.

What the race asks of your training

770 m of climbing in 43 km

The bike is longer than a standard Olympic distance and clearly hilly: 43 km and 770 m of climbing, in the Bauges regional nature park. Rides with climbs of several minutes, at a steady pace around threshold, prepare you better than flat volume.

Finding your legs on the flat

After the climbs, the run is flat, along the lake and through the Pâquier. Bricks of hill riding followed by 15 to 20 minutes at target race pace teach you to switch from grinding on the bike to a quick running stride.

Swimming in the lake, then under the Pont des Amours

The swim is in the lake and passes under the Pont des Amours; a wetsuit is on the official kit list. Swimming in open water a few times before the race helps with sighting and keeping your rhythm through the canal section.

A late-September race

With an 8 am start in late September, the race comes at the end of the season. You need to keep some intensity through the summer and peak late, rather than burning out on June races.

The plan below prepares the Olympique (M) format, for an athlete at intermediate level with 5 days available per week. Until the official date is out, the example is set for September 2027.

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.

“For triathlon, having all three sports in the same schedule really makes my life easier. I spend less time organising my training and I still enjoy following it just as much.”
Maxime · Triathlon
“At first I just wanted to try it. Now checking the next day’s session has become my little evening ritual 😊”
Sarah · Triathlon
“I used to spend more time looking for a plan than following one. Now I have my sessions, I know what to do and I stick to it. Really glad I tried it.”
Thomas · Running
“Training for my first half marathon and honestly, I’m getting into it! I even look at my next sessions ahead of time, when before I was mostly looking for an excuse not to go out 😂”
Camille · Running
“Simple to follow and really handy with the watch. I start my session and off I go.”
Julien · Running

Émilie · Trail
“What I like is no longer asking myself a thousand questions before going for a run. I follow the plan and I enjoy training.”
Nicolas · Trail
