7:26 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 Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Tighter than 89% of 100K races. Measured against 208 races of the same distance. Cut-off calculator →
Field size ~7 Tiny. You will run alone for most of it.
