What the course asks

Time limit 8 hours 8:53 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 1087 races of the same distance. Cut-off calculator →

Field size ~65 Mid-sized. Company early, well spread out by halfway.

DUV results for the 2026 edition (33.5mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
