Completing a hilly trail run - in 8 weeks

Experienced 8 weeks 3x/week
article rating 4.6/5 54

To be able to follow this plan, you must be able to run for 1 hour 30 minutes without stopping or have already run a half-marathon.

This plan is based on 3 training sessions a week structured into two 3-week cycles, with an easier week between each cycle and another before the trail.
Ideally, you will train on Tuesday, Thursday and Saturday to spread out sessions as much as possible.

I can’t guarantee you’re going to run during the steep parts of the trail but thanks to this plan, you should be able to finish without too much difficulty.

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

Week 1 - Cycle 1: you start gently.

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.

  • 02. 1h of jogging on flat terrain
  • 03. 1h15min of jogging on flat terrain

Week 2 - Cycle 1: boosting your weekend run

The weekend run will involve interval training to develop changes in speed and to gain in energy.

  • 05. 1h30min with 3x 5min at a fast pace

This week you’ll do your first long run. You must hydrate during these sessions, drinking at least a sip of water every 20 minutes.
