When is the Grand Raid Kiprun 3 Vallées 2027?

The dates have not been announced yet. In 2026, the event ran from 30 July to 2 August, and the Ultra des 3 Vallées started in Moûtiers on Thursday 30 July at 8 pm.

How long do you have to finish the Ultra des 3 Vallées?

In 2026, the race page set the finish cut-off at 2 am on Sunday 2 August, 54 hours after the start; the runner information page mentioned 55 hours. Intermediate cut-offs take slower runners out of the race, and they are brought back by shuttle.

Can you run the Ultra as a team?

Yes: the 170 km also runs as a relay, in teams of 8, mixed, women’s or men’s. Teams decide the relay order freely, but runners can only swap in a relay zone.

Grand Raid Kiprun 3 Vallées: how many weeks of preparation?

For an athlete at intermediate level, Endu builds a 25-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 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?

Not as a first long race: if you declare a beginner level, Endu flags it. Aim for a shorter race of the same kind first; Endu builds that preparation too.

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.

What the race asks of your training

A very mountainous 100-miler

12,000 m of climbing over 170 km is more than 70 m of ascent per kilometre on average. The organisers present it as one of the toughest 100-milers in Europe, across ridges, passes and high pastures. Long power-hiking climbs, with poles if you plan to use them, and big-vert weekends are the core of the preparation.

Starting in the evening, running two nights

The start is at 8 pm on Thursday and the finish cut-off falls at 2 am on Sunday: most runners spend at least two nights out. A headtorch with spare batteries is mandatory. A few long runs started in the evening teach you to manage sleep, eating and the night-time cold at altitude.

Cold at altitude

The 170 km mandatory kit includes a hooded waterproof jacket and a warm long-sleeved second layer, and the organisers can require more in extreme cold or heat. Train with your pack loaded with this kit and your water, and test in training what you will eat between aid stations.

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.

Elevation as the central variable

Weekly climbing volume, long hilly runs, downhill technique and power-hiking for ultras: a trail plan is not a road plan with bumps.

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.

“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
“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
“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
“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
