December Half Marathon Calendar event dates in grey are delinquent dates not updated by the race organizer yet. We strive to have dates 1 year out for December half marathons, but have no control of when they set, announce or update their dates.
December Half Marathons
The December Half Marathon Calendar is a complete simplistic listing of December half marathons 2025 in the USA. Currently the December half marathon schedule has 2025 half marathons, and December half marathons 2026 will be updated as they roll in from the 1/2 marathon race organizers. The December Half Marathon schedule identifies trail half marathons and walker friendly half marathons by a (T) symbol and a (W) symbol. The (T) means it is a TRUE trail half marathon (off road, switchbacks, etc) and a (W) means it is truly "official walker friendly" requiring the half marathon to allow a minimum of 18:32 mile pace, minimum 4 hours for participants to finish the 13.1 mile distance.
The December half marathon calendar features a complete listing of December half marathons in California, December half marathons in Texas, December half marathons in December, December half marathons in New York, December half marathons in Utah, December half marathons in Illinois, December half marathons in Ohio, December half marathons in Florida, and all other 1/2 marathons in December across the USA.
