Common Questions About Running a March 5K in Wisconsin
What is a good 5K time?
Across the 7 of these March 5K races with published results from past editions, the median finisher ran 34:18, and the median winning time was 18:35. So anything under 34:18 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 181 runners, across the 7 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 1:07:42.
