Common Questions About Running an October 5K in District of Columbia
How much does an October 5K cost to enter?

What is a good 5K time?
Across the 3 of these October 5K races with published results from past editions, the median finisher ran 33:58, and the median winning time was 17:36. So anything under 33:58 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 October 5K field?
The median one finished 439 runners, across the 3 of these October 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 1:25:09.
