River Rat Run
River Rat Run is an in-person road and trail race held in Yankton, South Dakota, on April 24, 2027. The event offers three chip-timed distances that run through the Lewis and Clark Lake Recreation Area, using newly paved trails that pass wooded areas along Lewis and Clark Lake and Lake Yankton. Chip timing is supported by video and manual iPad backup for added accuracy.
The event began in 2009 to honor a service member who died during Operation Iraqi Freedom. All race proceeds are directed to local nonprofit organizations and scholarships. The race is organized by the Yankton Athletic Events Association, a registered 501(c)(3) nonprofit.
Registration opens October 1, 2026. There is no race-day registration and the event is in-person only. The course descriptions provided by the organizers note a generally fast, mostly flat route that showcases park and campground areas.
