What the course asks

Time limit 14 hours 8:24 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 85% of 100K races. Measured against 208 races of the same distance. Cut-off calculator →

Field size ~13 Tiny. You will run alone for most of it.

DUV results for the 2025 edition (60km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
