What the course asks

6:51 min/km average. Firm. Sustained running. Long aid-station stops will cost you. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the tightest 50 mi cut-offs we track. Measured against 455 races of the same distance. Cut-off calculator →
Field size ~32 Small. Long stretches with nobody in sight.
