La DNF 2026

About this event

La DNF playfully reclaims trail running's most feared acronym. Set in the rolling terrain around Andilly in early November, this distinctive format challenges runners to complete as many loops as possible in 12 hours, with each lap growing progressively tougher. The twist: every loop must finish within 60 minutes or runners are eliminated. Three distances suit different ambitions — a 17km route with 480m of climbing, a 39km course gaining 1,185m, and a demanding 100km ultra accumulating 3,000m of elevation. The format turns pacing into a strategic puzzle, where knowing when to push and when to recover during those precious between-loop minutes becomes as crucial as the running itself. Here, the DNF transforms from failure into an accepted part of the challenge.
