What the course asks

Time limit 29 hours 21:45 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 445 races of the same distance. Cut-off calculator →
Field size ~42 Small. Long stretches with nobody in sight.

DUV results for the 2025 edition (50mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
