When should I sign up for a June 5K?
As early as you can. 10 of these June 5K races already have a price increase on the calendar, and 9 are open for entry right now. Another 9 have published an opening date and have not opened yet.
How much does a June 5K cost to enter?
The typical entry is $25, with paid entries running from $15 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 12 of these June 5K races with published results from past editions, the median finisher ran 36:44, and the median winning time was 18:20. So anything under 36:44 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 121 runners, across the 12 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 1:08:56.
