What the course asks

Time limit 32 hours 11:56 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. About average for a 100 mi. Measured against 30 races of the same distance. Cut-off calculator →

DUV results for the 2026 edition (100mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
