What the course asks
Time limit 12 hours
13:51 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 68% of 50K races. Measured against 1087 races of the same distance. Cut-off calculator →
Field size ~30 Small. Long stretches with nobody in sight.
