Common Questions About Running an April 5K in Illinois
When should I sign up for an April 5K?
As early as you can. 6 of these April 5K races already have a price increase on the calendar, and 9 are open for entry right now. Another 4 have published an opening date and have not opened yet.
How much does an April 5K cost to enter?
The typical entry is $30, with paid entries running from $10 up to $40. 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 6 of these April 5K races with published results from past editions, the median finisher ran 37:31, and the median winning time was 21:11. So anything under 37:31 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 147 runners, across the 6 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.
5K Races in Other Months
March and May sit either side of April, which is where most people look next when a date does not fit.
