Half Marathon races near Oklahoma City

Oklahoma City Training Notes

Oklahoma City hosts 10 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals put a lot of base miles on Lake Hefner, and the loop runs 10 miles all the way around. Lake Hefner Trails have very little traffic to contend with, good scenery, and half-mile marks when you want honest intervals. The Hefner-Overholser Trails connect the lakes, and Lake Overholser gives weekend runners about 8 miles around. The Oklahoma River Trails give both banks 13 miles total through the Boathouse District. The Landrunners, also known as the Oklahoma City Running Club, keep the scene connected. The Oklahoma City Memorial Marathon is the anchor event, with Hometown Half Marathon & 5K/10K also in the mix.

Riders use Lake Hefner Trail, Oklahoma River Trails, Katy Trail, Overholser Trail, Bluff Creek Trail, and Lake Stanley Draper Trail for weekday spins and longer Z2. Great Rides Oklahoma City runs the Lake Hefner Loop as a 10-mile ride from Stars and Stripes Park, and Oklahoma Bicycle Society gives roadies another local hub. Gravel riders hit Bluff Creek, Dam gravel, River Road, and Honey Grav in Kingfisher County. Honey Grav has smooth gravel and little elevation gain, but the route has no refuel or water stops until mile 32.5. Arcadia Loop brings the real climbing with 1,033 m elevation near Edmond.

Spring and fall are the best months, especially when the maintained sidewalks sit under massive trees and the fall color shows up. Summer brings hot, humid work, and the south or south-southeast wind can turn Z2 into a headwind session fast. The temperature hits 8°C on nearly 70 days. The temperature can drop to 7°C, and northerly winds make it feel colder. Ice storms and snowstorms happen sporadically, so runners and cyclists shift routes, layers, and start times when the weather flips.
