What the course asks
Time limit 12 hours
14:24 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 69% of 50K races. Measured against 982 races of the same distance. Cut-off calculator →
Field size ~122 Mid-sized. Company early, well spread out by halfway.
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.
