About average for Colorado half marathons
The fastest quarter of the 2026 half marathon field finished under 1:58:48, against 1:56:43 in a typical Colorado half marathon, so times here are about average.
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 May 2 the day usually runs from 39°F at dawn to 67°F in the afternoon, with measurable rain on about 27% of days. Cold snaps dip to 34°F and hot years reach 76°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.
