What the course asks
Time limit 10 hours
9:14 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Tighter than 84% of 50 mi races. Measured against 455 races of the same distance. Cut-off calculator →
Field size ~153 Mid-sized. Company early, well spread out by halfway.
DUV results for the 2025 edition (65km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
