How fast is it?
About average for Colorado half marathons
The fastest quarter of the 2026 half marathon field finished under 1:59:06, 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.
