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.

Frequently asked questions
- TGCM (Trail des Gorges du Chambon) — Gouyat: how many weeks of preparation?
- For an athlete at intermediate level, Endu builds a 11-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.
- Is this plan well built?
- Pass at Endu’s plan check, the same as for any plan: 14 of 14 checks passed. A 11-week build (recommended minimum: 8); a longest run never more than 10% above the previous month’s; volume rising at most 12% from one week to the next; 93% of the time at easy effort; a taper cutting volume by 51% in race week. The rules and their sources are public on endu.fr/en/controle-technique.
- How many sessions per week?
- This example has 4 sessions per week. You choose 3 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.
