What the course asks

Time limit 14.5 hours 17:24 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 89% of 50K races. Measured against 1034 races of the same distance. Cut-off calculator →

Field size ~32 Small. Long stretches with nobody in sight.

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