When is the MaXi-Race 2027?

From Friday 28 to Sunday 30 May 2027, in Annecy. The solo tOur du Lac starts in the night from Friday to Saturday 29 May, between 1:25 am and 3:20 am depending on your wave; bibs are collected the day before, Friday 28 May, at the MaXi-Village, in a slot booked in advance.

How do you enter the MaXi-Race 2027?

Pre-registration is closed: it ran from 1 to 7 October 2026, followed by a selection of runners. What remains is the waiting list, open to everyone on Sportips since 16 October 2026, and the official bib exchange, from 20 October 2026 to 15 April 2027. No bibs are issued on race day.

What are the tOur du Lac cut-offs?

The time limit is 24 hours. According to the 2027 race table, you must leave Doussard (km 46) before 1:30 pm, Bellecombe-en-Bauges (km 67) before 6:20 pm and the Semnoz (km 85) before 12:45 am, to finish in Annecy before 3:30 am on Sunday.

Do you need points to run the tOur du Lac?

No: no index is required to enter, but the organisers recommend a Betrail index of 40 points to finish. The Demi tOur, on the other hand, requires 40 Betrail points. Start waves are allocated by Betrail index.

Yes, except where signs say otherwise. On the tOur du Lac, they are banned even in hand for the first 20 km, where they must be stowed on your pack or belt, then on two 500 m sections near the Col de Bornette.

MaXi-Race (Lac d'Annecy): 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 4 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 2027 course

Start from the Quai de la Tournette, in Annecy, in the middle of the night, clockwise. First climb over the Veyrier massif, then Belossier (km 15) and the light aid station at Alex (km 17), with poles banned until km 20. The course passes the light aid station at Montremont (km 28) and Pré Vérel (km 31), then drops to the Doussard life base, at the far end of the lake (km 46, nearly 3,000 m of climbing), where crews and the mid-race drop bag are allowed. Second part in the Bauges: Col de Bornette (km 61), the light aid station at Bellecombe-en-Bauges (km 67), a quarry (km 71), then the climb to the Semnoz life base (km 85). The last 15 km, with no aid station, drop through the forest to the lakeshore and the finish at the MaXi-Village, Parking des Marquisats, after about 100 km and 5,500 m of climbing.

What the race asks of your training

A first climb in the dark, without poles

The start is between 1:25 am and 3:20 am, and the first climb, over the Veyrier massif, is done by headtorch. Poles are banned, even in hand, for the first 20 km, and on two 500 m sections near the Col de Bornette. Practise climbing without poles, and do a few long runs started in the middle of the night.

5,500 m of climbing in the foothills

Doussard comes after about 46 km and nearly 3,000 m of climbing, then the crossing of the Bauges and the climb to the Semnoz add another 2,300 m over 39 km. Long climbs at a brisk hiking pace, mountain weekends and descent work on trails prepare you for this profile better than track intervals.

Semi-self-sufficiency on water

There is no water supply in the mountain sections, only water points in some valleys, and the race sheet requires you to leave Doussard with 1.5 litres of water and the Semnoz with 1 litre. The last section, from the Semnoz to Annecy, has no aid station. The rules also require a headtorch, a waterproof breathable jacket, a reusable cup, a survival blanket, a phone and a whistle. Do your long runs with a loaded pack and test your gels or drink in training.

A build-up through winter and spring

For a race at the end of May, a 16- to 20-week build-up starts in January, when high trails are still snowbound: low-mountain hills, stairs or an inclined treadmill do the climbing work. The biggest long runs fall in April and early May. The cut-offs, at Doussard at 1:30 pm and on the Semnoz at 12:45 am, leave little margin for the last waves.

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.

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

Antoine · Swimrun
“I run more regularly and, above all, with more desire. For that alone, I’m delighted.”
