What the course asks

Time limit 11 hours 6:36 min/km average. Firm. Sustained running. Long aid-station stops will cost you. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the tightest 100K cut-offs we track. Measured against 214 races of the same distance. Cut-off calculator →

Field size ~394 Large. Rarely out of sight of another runner.

DUV results for the 2026 edition (100km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.

Hydration Vests Flask capacity for 100 km, without the bounce.
Headlamps 100 km almost certainly means running into the night.
