Common Questions About Running a January 5K in Colorado

When in January are most 5K races held?

The busiest weekend in Colorado is January 9 and January 10, with 3 of them. Another 3 fall on a weekday, which is worth knowing if you are traveling for one.

What is a good 5K time?

Across the 7 of these January 5K races with published results from past editions, the median finisher ran 34:22, and the median winning time was 18:49. So anything under 34:22 puts you in the faster half of a typical field. That is the middle of these RunSignup fields, walkers and charity entrants included, not a national average.

How big is a typical January 5K field?

The median one finished 153 runners, across the 7 of these January 5K races with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 1:05:36.
