Common Questions About Running a June 5K in Illinois
What is a good 5K time?
Across the 13 of these June 5K races with published results from past editions, the median finisher ran 39:22, and the median winning time was 17:37. So anything under 39:22 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 June 5K field?
The median one finished 240 runners, across the 13 of these June 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 1:09:01.
