Aquarium Run Half Marathon, 10K, 5K & 1-Mile

Sunday, September 20, 2020 • Jenks, OK • Course Map

Organized both as a fundraiser for the educational programs at nearby Tulsa’s Oklahoma Aquarium and as a way to raise awareness about the importance of physical fitness and a healthy lifestyle for local residents, Jenks’s Aquarium Run features distances to suit runners of widely varying abilities.

The race features its 13.1-mile half marathon as well as 10K and 5K runs and the one-mile “fun run” for both runners and walkers. Between 700 and 800 runners cross the finish line each year the half marathon and 5K events, with more than 300 of those participants running in the half-marathon alone.

The race itself starts and finishes just outside the Oklahoma Aquarium on Aquarium Drive, overlooking the Arkansas River flowing by, and takes runners on an out-and-back course along the streets and roadways that branch out from the Aquarium, along a mostly flat and fast course.

The event also features a post-race party at the Aquarium’s McGraw Beach on the banks of the river, as well as free admission to the Aquarium on the day of the race for all registered runners and walkers in the event.
