What the course asks

Time limit 20 hours 12:00 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 72% of 100K races. Measured against 208 races of the same distance. Cut-off calculator →

Field size ~173 Mid-sized. Company early, well spread out by halfway.

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.

RunRepeat found the Brooks Catamount 3 to have a cozier upper that enhances the overall fit, though breathability and durability could be better. iRunFar noted…
