How fast is it?

Faster than most Colorado trail 10Ks

The fastest quarter of the 2025 10K field finished under 56:00, against 1:08:56 in a typical Colorado trail 10K, so times here run 19 percent faster.

  • 10 Mile: Faster than most US trail 10-mile races. The fastest quarter of the 2025 10-mile race field finished under 1:35:22, against 1:39:05 in a typical US trail 10-mile race, so times here run 4 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.

Typical race-day weather

Around October 3 the day usually runs from 46°F at dawn to 78°F in the afternoon, with measurable rain on about 8% of days. Cold snaps dip to 41°F and hot years reach 86°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.
