Common Questions About Running a January 5K in California
What is a good 5K time?
Across the 33 of these January 5K races with published results from past editions, the median finisher ran 37:48, and the median winning time was 17:58. So anything under 37:48 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 162 runners, across the 33 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 1:14:00.
Are there trail 5K races in California in January?
Yes, 3 races around California get you off the pavement: 2 are trail races, and 1 mixes road and trail.
