How much does a May 10K cost to enter?

So anything under 1:05:29 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 May 10K field?
The median one finished 80 runners, across the 5 of these May 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 1:45:50.
