What the course asks

Time limit 14 hours 13:08 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 75% of 50 mi races. Measured against 445 races of the same distance. Cut-off calculator →

Field size ~586 Large. Rarely out of sight of another runner.

DUV results for the 2025 edition (64km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
