What the course asks
Time limit 12 hours
15:00 min/km average. Generous. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. More forgiving than 78% of 50K races. Measured against 1046 races of the same distance. Cut-off calculator →
Field size ~126 Mid-sized. Company early, well spread out by halfway.
DUV results for the 2025 edition (48km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
