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 10K in Georgia
When in December are most 10K races held?
The busiest weekend in Georgia is December 12 and December 13, with 7 of them. Another 3 fall on a weekday, which is worth knowing if you are traveling for one.
What is a good 10K time?
Across the 9 of these December 10K races with published results from past editions, the median finisher ran 1:01:48, and the median winning time was 40:49. So anything under 1:01:48 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 44 runners, across the 9 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 1:41:35.
