What the course asks

Time limit 7 hours 8:12 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the tightest 50K cut-offs we track. Measured against 1007 races of the same distance. Cut-off calculator →

Field size ~26 Small. Long stretches with nobody in sight.

DUV results for the 2026 edition (51.2km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
