What the course asks

Time limit 20 hours 18:45 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 50 mi cut-offs we track. Measured against 455 races of the same distance. Cut-off calculator →

Field size ~14 Tiny. You will run alone for most of it.

DUV results for the 2026 edition (40mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
