What the course asks

Time limit 48 hours 11:37 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the tightest 200 mi + cut-offs we track. Measured against 13 races of the same distance. Cut-off calculator →
Field size ~1 Tiny. You will run alone for most of it.

DUV results for the 2025 edition (248km) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.

Course Notes

The 248km trail leads all the way around the island from Rønne to Rønne and back again. So total two loops - first clockwise and then counter clockwise
