26 Ultra races in December 2026
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
Ultra races do not spread evenly across December. The busiest weekend is December 5 and December 6, with 7 of them. Another 8 fall on a weekday.
By the numbers
The December Ultra 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 26 Ultra races, against 45 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 5 and December 6, with 7 Ultra races on those two days, and the single busiest day is Saturday, December 5 with 7. Another 8 fall on a weekday, which is worth knowing if you are traveling for one.
As early as you can. 13 of these December Ultra races already have a price increase on the calendar, and 16 are open for entry right now. Another 9 have published an opening date and have not opened yet.
The typical entry is $90, with paid entries running from $15 up to $9999, and 1 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 9 of these December Ultra races with published results from past editions, the median finisher ran 7:20:38, and the median winning time was 4:37:16. So anything under 7:20:38 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 46 runners, across the 9 of these December Ultra 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 10:25:19.
Georgia has 7, California has 3, Florida has 3, Texas has 3, Virginia has 2. If you are willing to travel, those are the states where a December weekend gives you the most to choose from.
Yes, 5 races around the United States get you off the pavement: 5 are trail races. 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.
