Build your running base to 40–50 miles per week on trails and complete a trail marathon before entering your first 50K. This step validates your base fitness, teaches you trail-specific skills (climbing, descending, aid station use), and builds confidence for the extra 8K of a 50K.
Proof required
Submit: trail marathon finisher certificate or results page showing name and finish time; Strava or GPS training log showing 40+ miles/week over 4+ consecutive weeks.
What gets checked
- Marathon is a trail event on a certified course — road marathons alone do not develop the terrain skills needed for 50K ultras
- Training log shows 40+ miles/week consistently over 4 weeks, not a single peak week
- Both marathon result and training log are from GPS or official sources — not self-reported
