Common Questions About Running an August 5K in Washington
What is a good 5K time?
Across the 3 of these August 5K races with published results from past editions, the median finisher ran 36:25, and the median winning time was 18:38. So anything under 36:25 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 August 5K field?
The median one finished 153 runners, across the 3 of these August 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 1:11:00.
