What the field actually runs
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 Sep 22, 2026.
When in December
10K races do not spread evenly across December. The busiest weekend is December 12 and December 13, with 133 of them. Another 22 fall on a weekday.
By the numbers
The December 10K races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
It is one of the busier months. December carries 413 10K races, against 694 in October, which is the fullest month of the year. There is a real choice of dates here, with less competition for entries than the peak of the season.
The busiest weekend is December 12 and December 13, with 133 10K races on those two days, and the single busiest day is Saturday, December 12 with 114. Another 22 fall on a weekday, which is worth knowing if you are traveling for one.
As early as you can. 97 of these December 10K races already have a price increase on the calendar, and 400 are open for entry right now. Another 12 have published an opening date and have not opened yet.
The typical entry is $30, with paid entries running from $10 up to $500, and 3 that are free to enter. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
Across the 150 of these December 10K races with published results from past editions, the median finisher ran 1:03:59, and the median winning time was 43:38. So anything under 1:03:59 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.
The median one finished 17 runners, across the 150 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 1:37:57.
Florida has 67, Texas has 58, California has 47, Georgia has 23, Washington has 19. If you are willing to travel, those are the states where a December weekend gives you the most to choose from.
Yes, 10 races around the United States get you off the pavement: 4 are trail races, and 6 mix road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
November and January sit either side of December, which is where most people look next when a date does not fit.
