What the course asks
Time limit 10 hours
12:00 min/km average. Comfortable. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. About average for a 50K. Measured against 1087 races of the same distance. Cut-off calculator →
Field size ~97 Mid-sized. Company early, well spread out by halfway.
