Faster than most Colorado half marathons
The fastest quarter of the 2026 half marathon field finished under 1:53:10, against 1:56:43 in a typical Colorado half marathon, so times here run 3 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 August 22 the day usually runs from 60°F at dawn to 89°F in the afternoon, with measurable rain on about 12% of days. Cold snaps dip to 57°F and hot years reach 95°F.
