What the course asks

Time limit 13 hours 7:48 min/km average. Firm. Sustained running. Long aid-station stops will cost you. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Tighter than 88% of 100K races. Measured against 214 races of the same distance. Cut-off calculator →

Field size ~16 Tiny. You will run alone for most of it.

DUV results for the 2024 edition (50km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
