When in October are most Half Marathon races held?

The busiest weekend in Oklahoma is October 24 and October 25, with 3 Half Marathon races on those two days, and the single busiest day is Saturday, October 10 with 2. Every one of them is on a Saturday or a Sunday.

How much does an October Half Marathon cost to enter?

So anything under 2:19:02 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 Half Marathon field?

The median one finished 49 runners, across the 4 of these October Half Marathon 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 3:28:37.
