A 16-week plan for your first 50K trail ultra, for runners who already have a half marathon or marathon behind them. Five runs a week: a quality session, an easy run, hills or tempo, a long trail run on Saturday and a back-to-back run on Sunday. The long run builds to 4 hours, recovery weeks fall at 4, 8 and 12, the load peaks in week 13, and a three-week taper leads into race day. Efforts are set by RPE.

How it works in The Next Race

Add it to your calendar

Pick a start date, or pick your race date and the plan lines up behind it. You get your own copy, so you can move, edit or delete any session.

Set your zones

The test sessions set your training zones, so the targets fit your current fitness rather than someone else's.

Train with your devices

Workouts sync to Garmin and Wahoo, completed activities come back from Garmin, Strava and Polar, and indoor rides can run on a smart trainer.
