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.
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 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.
