River Rat Run - Yankton, South Dakota

River Rat Run stages chip-timed running events in the Lewis and Clark Lake Recreation Area. Participants may choose from the following distances:

  • Half Marathon
  • 10K
  • 5K

Each course uses newly paved trails that run through wooded areas along the shores of Lewis and Clark Lake and Lake Yankton, with two brief grass connectors between trail sections. The route offers open lake views and opportunities to see local wildlife; in winter, bald eagles are commonly observed.

Timing is provided by chip timing with video and manual iPad backup. All races begin at the Gavins Point Area picnic shelter at the east end of the beach parking lot. Packet pick-up is available the day before at Ace Bike & Fitness and there is also race-day check-in at the picnic shelter; a free park day pass for participant vehicles is provided at packet pick-up. No race-day registrations are accepted and there is no virtual option.

Race photography is provided by Berry’s Photography. The event began in 2009 to honor a service member who died in 2005 during Operation Iraqi Freedom, and all race proceeds are donated to select local nonprofit organizations. Visit the organization's website for the most recent information.
