What is a good 5K time?
Across the 19 of these May 5K races with published results from past editions, the median finisher ran 36:47, and the median winning time was 20:19.

How big is a typical May 5K field?
The median one finished 107 runners, across the 19 of these May 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 1:07:37.
