What the course asks

Time limit 8.5 hours 10:12 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Tighter than 77% of 50K races. Measured against 1007 races of the same distance. Cut-off calculator →

Field size ~62 Mid-sized. Company early, well spread out by halfway.

DUV results for the 2023 edition (50km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.

Course Notes

10km loop. 50km Solo runners complete the whole 50km as an individual and will certainly get a strong feeling of tunnel vision as 20km of their race will be underground!
