Experienced 12 weeks 3x/week
article rating 4.8/5 34

To follow this programme, you must have already completed a marathon or a trail of less than 40km.

This plan is based on 3 training sessions a week structured into three 3-week cycles, with an easier week between each cycle and another before the trail.

Ideally, you will train on Wednesday, Saturday and Sunday to spread out the sessions as much as possible and build up mileage over a short period.

This plan includes a limited number of sessions for such a challenging event. It’s essential to have solid trail experience for it to be successful.

You need to have Decathlon Coach application to launch this program !

Week 1 - Cycle 1: First long run.

Try to run as much as possible outdoors, alternating between different surfaces.
This will enable you to get used to running on uneven terrain and you’ll strengthen your muscles naturally.

  • 01. 1 hour 30 minutes of jogging on hilly terrain
  • 02. 1 hour 30 minutes of jogging on hilly terrain
  • 03. 2 hour of jogging on hilly terrain

Week 2 - Cycle 1: first hike run

You will go for a 3-hour "hike run" alternating between walking (uphill) and easy running (on flat terrain and downhill).

If you don't have any hills, do 5 minutes of brisk walking every 30 minutes to get used to switching between running and walking.

  • 04. 2 hour of jogging on hilly terrain
  • 05. 4 x 6min of hill training
  • 06. 3hr hike run

Week 3 - Cycle 1: increasing the distances
