Ninja 5K, 10K, and 13.1M

Prepare for an exhilarating challenge at the Ninja 5K, 10K, and 13.1M, taking place on Saturday, August 1, 2026, in scenic Stillwater, Oklahoma. This event, kicking off at 8:00 AM CDT, offers a fantastic atmosphere for runners of all levels to conquer their chosen distance: a spirited 5K, a determined 10K, or an enduring half marathon. The course is set within the beautiful Boomer Lake Park, featuring a paved out-and-back route that provides consistent terrain. The 5K covers the out-and-back once, the 10K twice, and the half marathon will test your endurance with four loops of a 3.28-mile segment.

Runners can anticipate typical race day conditions with highs around 94F and lows near 72F, and an 11% chance of precipitation, making for a warm but potentially refreshing summer run. The race starts and finishes conveniently at Shelter #3, adjacent to the Boomer Park Splash Pad on the west side of Boomer Lake. Be prepared for a self-sufficient race experience, as there are no aid stations along the course. However, participants can look forward to earning a well-deserved finisher medal upon completion, celebrating their accomplishment in this vibrant community event. Online registration is required in advance, as there will be no on-site registration.
