What the course asks

Time limit 17 hours 15:42 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 90% of 50 mi races. Measured against 455 races of the same distance. Cut-off calculator →
Field size ~2 Tiny. You will run alone for most of it.

DUV results for the 2024 edition (65km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
