10:22 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it.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 74% of 50K races. Measured against 1007 races of the same distance. Cut-off calculator →
Field size ~308 Large. Rarely out of sight of another runner.
