How fast is it?
About average for US trail 100Ks
The fastest quarter of the 2025 100K field finished under 14:39:07, against 14:32:29 in a typical US trail 100K, so times here are about average.
- 50K: Slower than most US trail 50Ks. The fastest quarter of the 2025 50K field finished under 6:53:57, against 6:08:34 in a typical US trail 50K, so times here run 12 percent slower.
- 10 Mile: Slower than most US trail 10-mile races. The fastest quarter of the 2025 10-mile race field finished under 1:53:25, against 1:39:05 in a typical US trail 10-mile race, so times here run 14 percent slower.
Compares the fastest quarter of each field, so walkers and first-timers do not skew it. It reflects the course and the field together: a flat course, cool weather, or a competitive crowd all make times faster.
