What is a good 10K time?
Across the 6 of these October 10K races with published results from past editions, the median finisher ran 1:05:39, and the median winning time was 42:40. So anything under 1:05:39 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 10K field?
The median one finished 51 runners, across the 6 of these October 10K 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 1:48:29.
