Faster than most US trail 50-mile races
The fastest quarter of the 2026 50-mile race field finished under 10:06:17, against 10:47:13 in a typical US trail 50-mile race, so times here run 6 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.
Around January 9 the day usually runs from 44°F at dawn to 63°F in the afternoon, with measurable rain on about 17% of days. Cold snaps dip to 38°F and hot years reach 73°F.
Based on 75 days within a week of the date over the last 5 years, from historical weather for the start area. Not a forecast.
