This four-day festival celebrates the burgeoning watersport haven the Boathouse District and Oklahoma River in Oklahoma City has become. Thursday kicks off at 6 p.m. with OGE NightSprints, which will be held nightly during the festival. Friday night’s activities include the Quixotic Cirque Nouveau, acrobatics staged atop the six-story SandRidge Sky Trail, along with fireworks. Saturday features more racing and revelry; the festival concludes Sunday with the INTEGRIS Jim Thorpe Courage Run, a one-mile family run and a 5k and 10 k run/walk.
