Oklahoma Half Marathons
The Oklahoma Half Marathon Calendar is a complete simplistic listing of Oklahoma half marathons. Currently the Oklahoma half marathon schedule has 2025 Oklahoma half marathons and 2026 Oklahoma half marathons as they roll in. Oklahoma half marathons 2025 & Oklahoma half marathons 2026 also identify 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 21k (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 Oklahoma half marathon calendar features a complete listing of Tulsa half marathons, Oklahoma City half marathons, Jenks half marathons, Ardmore half marathons, Woodward half marathons, Stillwater half marathons, Vinita half marathons, and any other 1/2 marathons in OK.
