What the course asks

Time limit 10 hours 10:43 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 50K races. Measured against 1087 races of the same distance. Cut-off calculator →

Field size ~149 Mid-sized. Company early, well spread out by halfway.

DUV results for the 2022 edition (35mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.

Course Notes

Essentially you’re going to be following the coastline round the entire island. Across firm sandy beaches, along gravel tracks, grassy dunes, sheep tracks, a few bogs and some rocky outcrops. There’s a few hills but nothing serious.
