When is Valtriman 2027?

The 2027 date is not announced yet. The 2026 edition took place on Saturday 30 and Sunday 31 May; earlier editions were held in mid or late May.

When does registration open for Valtriman 2027?

Not announced yet. For 2026 it opened on 15 November 2025 at 8 pm, online only. Places are limited: 700 on the V60 and V30, 300 on the V13.

How much does Valtriman cost?

In 2026: €25 for the V13, €35 for the V30, €45 for the V60 and €10 for the ValtriKids. Athletes without a licence add an Expérience day licence, from €4 to €22 depending on the race.

Does Valtriman offer a half distance?

No. The longest race is the V60: 1.5 km swim, 53.5 km bike and 10 km run.

Valtriman: 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 from the nautical base on Lac du Val Joly. The V60 swims one 1.5 km loop and exits at the transition area, in the heart of the resort. The bike leaves the resort for two loops through a Natura 2000 area, 53.5 km and 775 m of climbing, with an aid station at the transition exit. The run is two 5 km loops from the heart of the resort, 120 m of climbing, with an aid station on each lap and one at the finish. A wetsuit is mandatory below 16 °C and banned above 24 °C.

What the race asks of your training

A longer, hillier bike than a standard M

53.5 km instead of 40, with 775 m of climbing over two loops: the bike weighs more than on a classic Olympic distance. Extending rides towards 60 to 70 km with some hills prepares you to last to the end.

No drafting

Drafting is banned on every race: 12 m between bikes, and you pass cleanly. Everyone rides at their own pace, as in a time trial: threshold sessions on the bike, alone, prepare you better than group rides.

An afternoon start

The V60 starts at 1:30 pm. Doing a few key sessions in the early afternoon, and testing what you eat at lunchtime beforehand, avoids digestive surprises.

Two races in two days

The Challenge 90 links the V30 on Saturday and the V60 on Sunday. A few training weekends with key sessions on consecutive days teach you to go again on tired legs.

Endu runs its own plans through the plan check open to everyone: same public rules, same thresholds, same sources. The rules and their sources, and a check of your own plan.

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.

4.8/5

“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
“I took Endu to prepare a trail race with friends. I really like having my week already organised: it motivates me and I enjoy my runs more.”
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
“With work and the kids, I thought I’d struggle to follow a plan. In the end, having a structure helps me a lot. Running has found a real place in my week again, and it feels good!”
Julie · Trail
“A good find to prepare my swimrun! It’s nice to find a plan for this sport. I’ve recommended it to my teammate.”
Antoine · Swimrun
“I run more regularly and, above all, with more desire. For that alone, I’m delighted.”
Laura · Swimrun
