100 Mile Trail Training Plan

Turn Up to your 100 Mile Trail Event prepared
The aim of this 16 week plan is to teach you what to do every week to get your body in the best possible shape for your 100 Mile Ultra event.
Runners often enter an ultra, get over-excited, train too hard, get injured, or peak too early.
To avoid over doing it … or under doing it, the best way to approach your training is with a specific training plan that will help you to develop endurance and strength, and gradually increase volume, elevation, and intensity, so you peak at the right time for your 100 Mile event.
In 16 weeks from now, the aim of the plan is to have you feeling strong and prepared. Ready to really enjoy your ultra.
To give you an idea of what to expect, our beginner plan kicks off with a weekly volume of 50km and a long run of 20km. The advanced plan starts with a total weekly volume of 75km and a long run of 25km.
If these training volumes feel like a stretch right now, consider starting with our 100km trail plan instead. It’s better to build gradually than risk injury by doing too much too soon.
