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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 203 races of the same distance. Cut-off calculator →
Field size ~9 Tiny. You will run alone for most of it.

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.
