What the course asks

Time limit 30 hours 11:11 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Tighter than 70% of 100 mi races. Measured against 30 races of the same distance. Cut-off calculator →

Field size ~45 Small. Long stretches with nobody in sight.

DUV results for the 2026 edition (100km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.

Course Notes

The trail will take you through scree fields, valleys, and a 2.3-mile-long tunnel, all while running on crushed limestone at a grade no greater than 5% (and usually much less).
