Create my plan for MarathonFrequently asked questions
- Marathon, beginner level: how many weeks of preparation?
- For an athlete at beginner level, Endu builds a 17-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: 17 of 17 checks passed. A 17-week build (recommended minimum: 12); a longest run never more than 9% above the previous month’s; volume rising at most 8% from one week to the next; 93% of the time at easy effort; the longest session 3 weeks before the race; a taper cutting volume by 60% 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.
- 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.
