Common Questions About Running an April 5K in Illinois
What is a good 5K time?
Across the 11 of these April 5K races with published results from past editions, the median finisher ran 36:07, and the median winning time was 20:47. So anything under 36:07 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 April 5K field?
The median one finished 79 runners, across the 11 of these April 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 1:07:02.
