21 5K races in June 2027
What the field actually runs
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Sep 22, 2026.
When in June
5K races do not spread evenly across June. The busiest weekend is June 5 and June 6, with 8 of them. Another 2 fall on a weekday.
By the numbers
The June 5K races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
The busiest weekend in Illinois is June 5 and June 6, with 8 5K races on those two days, and the single busiest day is Saturday, June 5 with 7. Another 2 fall on a weekday, which is worth knowing if you are traveling for one.
As early as you can. 14 of these June 5K races already have a price increase on the calendar, and 12 are open for entry right now. Another 9 have published an opening date and have not opened yet.
The typical entry is $30, 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.
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.
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.
May and July sit either side of June, which is where most people look next when a date does not fit.
