Eagle 5K, 10K, & 13.1M at Stillwater, OK (27) 2026

The Eagle 5K, 10K, and 13.1M in Stillwater, Oklahoma, begins at 8:00 AM from Shelter #3 at Boomer Lake Park, located beside the Boomer Park Splash Pad on the west side of the lake. Three distances are offered on the same race morning: a 5K, a 10K, and a half marathon. Runners must register in advance through RunSignup, as there is no race-day sign-up at the park. Packet pickup is brief and near the start, opening 30 minutes before the race and closing 10 minutes before it begins. The races utilize straightforward out-and-back routes, with the distance determined by the number of repeats each runner completes. The 5K involves one out-and-back, the 10K requires two, and the half marathon uses a slightly longer out-and-back four times. This lap format ensures runners pass the start area repeatedly, where water, fruit or gummy snacks, and granola bars are available each lap and again after finishing. The course time limit is 3 hours and 30 minutes, and runners may carry their own hydration, nutrition, or other gear if they prefer more than what is provided at aid stations.
