Common Questions About Running a May 10K in Michigan
How much does a May 10K cost to enter?
The typical entry is $32, with paid entries running from $22 up to $35. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
What is a good 10K time?
Across the 6 of these May 10K races with published results from past editions, the median finisher ran 1:04:00, and the median winning time was 41:48. So anything under 1:04:00 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 93 runners, across the 6 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.
10K Races in Other Months
April and June sit either side of May, which is where most people look next when a date does not fit.
