What the course asks

Time limit 40 hours 14:54 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 83% of 100 mi races. Measured against 30 races of the same distance. Cut-off calculator →

Field size ~13 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.
