What the course asks
Time limit 29 hours
17:24 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the most forgiving 100K cut-offs we track. Measured against 208 races of the same distance. Cut-off calculator →
Field size ~4 Tiny. You will run alone for most of it.
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.
