What the course asks

Time limit 10 hours 9:23 min/km average. Tight. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Tighter than 82% of 50 mi races. Measured against 473 races of the same distance. Cut-off calculator →
Field size ~60 Mid-sized. Company early, well spread out by halfway.

DUV results for the 2023 edition (40mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.
