What the course asks
Time limit 13 hours
12:11 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. More forgiving than 66% of 50 mi races. Measured against 486 races of the same distance. Cut-off calculator →
Field size ~45 Small. Long stretches with nobody in sight.
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.
