How fast is it?
Faster than most US trail 50Ks
The fastest quarter of the 2026 50K field finished under 5:23:12, against 6:08:34 in a typical US trail 50K, so times here run 12 percent faster.
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.
