Common Questions About Running a June 5K in Iowa
How much does a June 5K cost to enter?
The typical entry is $30, with paid entries running from $22 up to $35, and 1 that are free to enter. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
What is a good 5K time?
Across the 4 of these June 5K races with published results from past editions, the median finisher ran 39:35, and the median winning time was 24:16. So anything under 39:35 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 156 runners, across the 4 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 1:10:04.
