When is the 2027 Tor des Géants?

The organisers have not announced the 2027 date yet. The 2026 edition started on Sunday 13 September, with the finish closing on Saturday 19 September.

How do you get a Tor des Géants bib?

Through a lottery after a paid pre-registration (€10 in 2026), or a guaranteed bib earned on some TORX circuit races. No ITRA points are required.

How long does it take to prepare for the Tor des Géants?

Endu plans 24 weeks of specific preparation, but it builds on years of mountain ultras: the Tor is not where you discover ultra running.

Tor des Géants: how many weeks of preparation?

For an athlete at advanced 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 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?

No. This race assumes several finished mountain ultras over 100 km: if you declare a beginner or intermediate level, Endu flags it. Start with a shorter race; 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.

Tor des Géants 2027: date, course and training plan

330 km · 24,000 m D+Courmayeur2027 edition: date not announced yet

The Tor des Géants (TOR330) loops around the Aosta Valley on its high trails: 330 km and 24,000 m of climbing from Courmayeur, with several passes above 3,000 m. There are no stages: each runner decides when and how long to sleep, within a 150-hour limit.

This race is for experienced ultra trail runners: finishing several mountain ultras over 100 km beforehand is recommended. The example below is built for an advanced athlete.

What the race asks of your training

Sleep is part of the race

Over 150 hours you spend several nights out. Long back-to-back outings over two or three days, partly at night, teach you to handle fatigue and sleep loss far better than one very long run.

Long climbs, and above all descents

24,000 m up is also 24,000 m down. Quads give out before the heart: eccentric strength work and downhill volume in the mountains come first in the final months.

Altitude and weather swings

The route swings from cold and sometimes snow above 3,000 m to heat in the valley floors. Training above 2,000 m in summer and testing all the mandatory kit in real conditions avoids nasty surprises.

Life bases set the rhythm

Six life bases (Valgrisenche, Cogne, Donnas, Gressoney, Valtournenche, Ollomont), each with a cut-off on the way in and out. Planning what you do there (eat, change, sleep) saves hours.

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.

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.

4.8/5

“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
