What the course asks

Time limit 14 hours 10:30 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. About average for a 50 mi. Measured against 455 races of the same distance. Cut-off calculator →

Field size ~292 Large. Rarely out of sight of another runner.

DUV results for the 2026 edition (60km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
