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 Nov 12, 2026.

Common Questions About Running a June 5K in Washington
When in June are most 5K races held?
The busiest weekend in Washington is June 12 and June 13, with 6 of them. Another 3 fall on a weekday, which is worth knowing if you are traveling for one.
What is a good 5K time?
Across the 9 of these June 5K races with published results from past editions, the median finisher ran 41:31, and the median winning time was 21:27. So anything under 41:31 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 June 5K field?
The median one finished 206 runners, across the 9 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 1:09:45.
