What the course asks
Time limit 7 hours
8:24 min/km average. Comfortable. Room to walk the climbs and stop at aid. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the tightest 50K cut-offs we track. Measured against 982 races of the same distance. Cut-off calculator →
Field size ~168 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.
