12 Weeks

Plan Description

A dedicated 12 week plan tailored for the unique demands of trail half marathons - up to 30km distance, written by an experienced trail running Coach and Mountain Runner, and ultra runner who has completed many of the hardest mountain races including Trofeo Kima, Tromso Skyrace, Glen Coe Skyline and UTMB.

Excellent for experienced road runners transitioning to trail.

It is 12 weeks long and features 2 or 3 build weeks followed by a recovery week and a two week taper.
Designed for trail races for events up to c.30km distance on trails and for athletes that are comfortable running for c. 2 hours. Great for those transitioning from road half and full marathons to trail with specific off road workouts.

Requires access to hills or a treadmill for certain workouts and a HR monitor.
Time based rather than distance.

Race day advice provided throughout the plan with downloadable guides.
