Haunted 5K, 10K, & 13.1M at Oklahoma City, OK

Haunted 5K, 10K, & 13.1M at Oklahoma City, OK is run in Oklahoma City on October 24, 2026. The half marathon (13.1 miles), the 10K and the 5K all start at 8 a.m. Awards cover both the fastest finishers and the best costumes, so creativity is rewarded alongside speed, and a medal waits for everyone who crosses the line in a field that keeps the pace honest.

Pick your distance by what your last month of training actually looked like, not by what you hoped it would be. A runner holding three or four sessions a week can race the 5K or 10K comfortably; the half wants a 12 week block with a weekly long run stretching toward 11 miles. Whichever you enter, the shared 8 a.m. start means everyone is finished and eating by mid-morning, which is a small but real advantage for a family entry.
