Is December a good month for a Half Marathon?
December sits in the middle of the year for the Half Marathon, carrying 298 against 376 in April and 102 in August. Enough to choose from, and easier to get into than the races at the peak of the season.

Half Marathons in December 2026
298 half marathons across the US in December 2026, sorted by date. Which weekends are busiest, what the fields actually run, entry fees, and where each one starts.
A December 13.1 puts you at the intersection of the fall racing season's final miles and the holiday calendar. Races lean festive, with Santa-themed events, family-friendly shorter distances on the same morning, and courses through decorated city streets. The mood is celebratory, but the logistics take more planning than usual.
Weather is the sharpest variable. The Northeast and Midwest can deliver cold, wind, and short days that demand real winter-race preparation, while Florida, coastal California, and the Southwest generally offer more forgiving conditions, though no December morning anywhere is guaranteed mild. Pick your region before you pick your race.
For most runners, December marks either a season finale or an early fitness check before a spring build. Either way, expect a body that is either well-trained from fall or just turning the corner from post-season rest. Be honest about which describes you before committing to a goal time.

Common Questions About Running a December Half Marathon
What should I wear for a December half marathon?
Dress in layers you can shed: a moisture-wicking base, a light wind layer on top, and gloves you can tuck into a waistband after the first few miles. In the South and coastal West, one light layer may be enough. In the North or Midwest, add a hat and consider tights over shorts. Overdressing is the more common mistake.
How does the holiday schedule affect race-day logistics?
December races frequently share weekends with holiday travel, family commitments, and venue conflicts. Packet pickup windows can be tighter than usual, parking near festive downtown courses fills faster, and some races draw spectators who are there for the atmosphere rather than the run. Build in extra time for everything and confirm pickup hours well in advance.
Is a December half marathon a good option for a beginner?
Yes, with honest preparation. The festive atmosphere and multi-distance formats at many events make them welcoming, and a runner who started a training plan in September has enough time to be ready. The added variable is weather: a beginner who has only trained in mild conditions should practice in cold and wind before race morning, not encounter them for the first time.
How far in advance should I start training for a December half marathon?
A full summer of structured build is the comfortable path: starting in late August or September gives enough weeks to develop an aerobic base, add mileage, and taper before race day. Runners coming off a fall marathon can shorten that window and treat December as a fitness check rather than a peak event, keeping expectations realistic.
When in December are most half marathons held?
The busiest weekend is December 12 and December 13, with 95 of them, 79 of those on Saturday, December 12. Another 19 fall on a weekday, which is worth knowing if you are traveling for one.
What is a good Half Marathon time?
Across the 118 of these December half marathons with published results from past editions, the median finisher ran 2:09:08, and the median winning time was 1:35:17. So anything under 2:09:08 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 Half Marathon field?
The median one finished 12 runners, across the 118 of these December half marathons 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 3:02:37.
Which states have the most December half marathons?
Florida has 49, California has 39, Texas has 38, Georgia has 16, North Carolina has 14. If you are willing to travel, those are the states where a December weekend gives you the most to choose from.
Are there trail half marathons in December?
Yes, 11 races around the United States get you off the pavement: 6 are trail races, and 5 mix road and trail.
