Common Questions About Running a May 10K in Michigan
What is a good 10K time?
Across the 11 of these May 10K races with published results from past editions, the median finisher ran 1:02:20, and the median winning time was 40:51. So anything under 1:02:20 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 May 10K field?
The median one finished 70 runners, across the 11 of these May 10K 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 1:51:20.
