What the course asks

Time limit 24 hours 14:24 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. More forgiving than 86% of 100K races. Measured against 208 races of the same distance. Cut-off calculator →
Field size ~18 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.
