What the course asks

Time limit 64 hours 22:20 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 100 mi cut-offs we track. Measured against 29 races of the same distance. Cut-off calculator →

Field size ~47 Small. Long stretches with nobody in sight.

DUV results for the 2026 edition (172km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
