How much does a December 10K cost to enter?

What is a good 10K time?
Across the 3 of these December 10K races with published results from past editions, the median finisher ran 1:00:55, and the median winning time was 51:10. So anything under 1:00:55 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 December 10K field?
The median one finished 3 runners, across the 3 of these December 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 1:05:58.
