What the course asks

Time limit 36 hours 13:25 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 67% of 100 mi races. Measured against 30 races of the same distance. Cut-off calculator →

Field size ~48 Small. Long stretches with nobody in sight.

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.
