How fast is it?

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.

  • 5K: About average for Colorado 5Ks. The fastest quarter of the 2026 5K field finished under 30:05, against 29:37 in a typical Colorado 5K, so times here are about average.
  • 10K: About average for Colorado 10Ks. The fastest quarter of the 2023 10K field finished under 56:48, against 55:16 in a typical Colorado 10K, 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.

Typical race-day weather

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.

Based on 85 days within a week of the date over the last 5 years, from historical weather for the start area. Not a forecast.
