How many weeks to prepare for Ceven Trail?

For an athlete at intermediate level, Endu builds a 24-week preparation. If your race is closer, the plan compresses phases while keeping the taper; if it's further away, it extends the base phase.

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: every session exports as .fit, the format read by Garmin, Coros, Suunto, Polar and Wahoo. Import it in your watch app and the guided workout appears on your wrist.

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.

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 VMA or a reference performance. A VMA 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

.fit export compatible with Garmin, Coros, Suunto, Polar: the guided workout shows up on your wrist, step by step.

Your plan, not a template athlete's

This plan is generated for an athlete at intermediate level training 4 times a week. Yours will be calibrated on your VMA, your available days and your feedback after every session. 3 minutes. 14-day trial, cancel anytime.
