What the course asks
Time limit 29 hours
24:51 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the most forgiving 50 mi cut-offs we track. Measured against 455 races of the same distance. Cut-off calculator →
Field size ~16 Tiny. You will run alone for most of it.
DUV results for the 2025 edition (70km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
