Common Questions About Running a March 5K in Michigan
What is a good 5K time?
Across the 15 of these March 5K races with published results from past editions, the median finisher ran 35:36, and the median winning time was 18:39. So anything under 35:36 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 150 runners, across the 15 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 1:07:20.
