How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Nov 12, 2026.

Common Questions About Running a December 5K in Oklahoma
When in December are most 5K races held?
The busiest weekend in Oklahoma is December 5 and December 6, with 15 of them, 14 of those on Saturday, December 5. Another 2 fall on a weekday, which is worth knowing if you are traveling for one.
What is a good 5K time?
Across the 13 of these December 5K races with published results from past editions, the median finisher ran 35:30, and the median winning time was 17:49. So anything under 35:30 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 5K field?
The median one finished 122 runners, across the 13 of these December 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 1:05:03.
