Plan Description

This training plan starts with mileage in the mid-20s per week and builds gradually up to a peak in the mid-50s, getting you to the start line of a 50km trail race having completed a short muscular endurance strength phase and sustained Zone 3 intensity.

The first long run duration is a few hours, so you should have enough mileage in your legs for that to feel doable. If you aren't quite there, our beginner plan may be a better fit.
