Go the distance, on your feet and on your terms.
Ultras are run by time and effort, not pace. Your plan builds long days on feet, adds hills and back-to-back runs where you can, and plans the race around aid stations and fuelling.

Who this plan is for
Runners who already have a marathon or long race behind them and want to step up to a trail marathon, 50K, 50 miles, 100K or 100 miles. It is a training tool, not medical advice.
Are you ready to start?You run four or more times a week, manage long runs of two hours or more, and have a marathon or long race behind you. A guide, not a test. If you are unsure, start with the plan before this one.
How it is built
- Long runs measured in time on feet, with hills and terrain you choose
- Back-to-back long days on weeks where you can run five or more days
- A race-day plan with an aid-station table, fuelling and gear, and a taper that cuts volume before the start
Questions about the Ultra plan
Are ultra sessions given as paces?
Mostly not. Terrain makes pace unreliable, so ultra sessions are set by time and effort, and runs are judged on time on your feet rather than pace.
Which ultra distances can I train for?
Trail marathon, 50K, 50 miles, 100K and 100 miles. You can add the race's climbing and say whether it is technical trail, mixed or road.
Do I need to have run a marathon first?
It helps, and we suggest a solid base before you begin. The plan builds from your current weekly volume, and tells you if the goal is further away than your training allows.
