What the course asks

Time limit 28 hours 16:48 min/km average. Generous. Walkable throughout for most of the field. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the most forgiving 100K cut-offs we track. Measured against 208 races of the same distance. Cut-off calculator →
Field size ~204 Large. Rarely out of sight of another runner.

DUV results for the 2025 edition (100km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
