How many weeks to prepare for Swimrun?

For an athlete at intermediate level, Endu builds a 15-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 3.9 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.

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.
