Common Questions About Running a March 5K in California
What is a good 5K time?
Across the 18 of these March 5K races with published results from past editions, the median finisher ran 38:21, and the median winning time was 19:06. So anything under 38:21 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 March 5K field?
The median one finished 205 runners, across the 18 of these March 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 1:22:31.
Are there trail 5K races in California in March?
Yes, 3 races around California get you off the pavement: 1 is a trail race, and 2 mix road and trail.
