This Oklahoma City event gets underway at 8:00 AM at Lake Stanley Draper, with packet pickup available for 30 minutes before the start and closing 10 minutes before race time. You'll need to register ahead of time on RunSignup since there's no day-of registration available. The 5K and 10K both use out-and-back loops (with the 5K covering the course twice and the 10K four times), while the 13.1-mile option repeats its out-and-back loop six times, and all distances must be completed within 3 hours and 30 minutes.
