Luchon Aneto Trail: how many weeks of preparation?

For an athlete at intermediate level, Endu builds a 21-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 2026 course

Start from the Casino park in Luchon at 5 am. The Ultra LAT climbs through the woods to the Hospice de France (aid station around km 15), then to the Port de Vénasque, on the Spanish border, facing the Maladeta and the Aneto, before dropping back to the Hospice de France (around km 30). Back to Luchon around km 44, at the aid station where families and clubs wait. The course then heads up the Larboust valley to the Granges d’Astau (around km 59), climbs to Lac d’Oô and the Col d’Espingo, on the GR10 (around km 64), then crosses the Hourquette des Hounts Secs to reach the Superbagnères ski station (around km 75). Last descent to Luchon: 84 km on the official GPX track, 5,300 m of climbing announced.

What the race asks of your training

The cut-offs come early

You must reach the Hospice de France by 8 am on the way out, 3 hours after the start, and be back there by noon. You need to climb fast early on without burning out: threshold hill sessions and long uphill runs at race pace pay off here.

High mountains and the night

The route crosses the Port de Vénasque, on the Spanish border, and ends at night for the last runners (finish closes at 1 am). Training at altitude from early summer and a few headlamp runs prepare you for both.

Running with 2 litres of water

Aid stations are about 15 km apart and the mandatory kit includes a 2-litre water reserve, a waterproof jacket, a hat and gloves. Do long runs with a loaded pack so your back and shoulders get used to it.

A spring build-up, with possible snow

For an early-July race, most of the build-up happens from April to June, while the peaks are still snowy. On race day too, some sections may still be snow-covered: the organisers can then make light crampons, long trousers and a warm layer mandatory. Train for steep descents and your quads, not only for the climbs.

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.

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.”

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.”

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

“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 😊”
