River Rat Run

River Rat Run is an annual set of chip timed races held at the Gavins Point area of the Lewis and Clark Lake Recreation Area near Yankton, South Dakota. The event offers these distances:

  • 5K (3.1 miles)
  • 10K (6.2 miles)
  • Half Marathon (13.1 miles)

All courses use newly paved trails that run through wooded sections and along the shores of Lewis and Clark Lake and Lake Yankton, with two short grass connectors between trail segments. Timing uses chips with video and manual iPad backup. The route provides wide lake views and opportunities to see local wildlife, including winter sightings of bald eagles.

Prizes are awarded to the overall male and female winners and to first and second place male and female finishers in age divisions 1–19, 20–29, 30–39, 40–49, 50–59, 60–69, and 70–99. Finisher medals are provided only to half marathon participants. Race shirts are available for registered runners. Runners must wear a visible bib for the entire race or risk disqualification. No refunds are offered and no awards or shirts will be mailed. Packet pick-up is available the day before at Ace Bike & Fitness, 2404 Broadway, Yankton. No new race-day registrations will be accepted.

The event began in 2009 to honor a fallen service member and donates its proceeds to local nonprofit organizations. Visit the organization's website for the most recent information.
