Runners follow an out-and-back course that runs largely along the banks of the Arkansas River at Jenks’s Aquarium Run Half Marathon, which starts and finishes on Aquarium Drive, in front of the Oklahoma Aquarium. From there, runners follow the trails that parallel the roadways and then cross over the river at Main Street/East 96th Street, and run the paved pathways that run alongside the river for most of the rest of the race.
