Common Questions About Running a September 5K in Ohio
What is a good 5K time?
Across the 9 of these September 5K races with published results from past editions, the median finisher ran 39:24, and the median winning time was 19:38. So anything under 39:24 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 September 5K field?
The median one finished 195 runners, across the 9 of these September 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 1:20:24.
