13 5K 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
5K races do not spread evenly across December. The busiest weekend is December 12 and December 13, with 6 of them. Another 1 fall on a weekday.
By the numbers
The December 5K races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
The busiest weekend in Arizona is December 12 and December 13, with 6 5K races on those two days, and the single busiest day is Saturday, December 12 with 5. Another 1 fall on a weekday, which is worth knowing if you are traveling for one.
As early as you can. 6 of these December 5K races already have a price increase on the calendar, and 13 are open for entry right now.
The typical entry is $30, with paid entries running from $15 up to $54.99. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
Across the 4 of these December 5K races with published results from past editions, the median finisher ran 37:25, and the median winning time was 20:01. So anything under 37:25 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 239 runners, across the 4 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 1:12:15.
Yes, one race around Arizona gets you off the pavement: 1 mixes 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.
