What the course asks

Time limit 13 hours 9:45 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 79% of 50 mi races. Measured against 455 races of the same distance. Cut-off calculator →

Field size ~168 Mid-sized. Company early, well spread out by halfway.

DUV results for the 2026 edition (50mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
