Taming of the Slough - SUNDAY September 12, 2021

Taming of the Slough Registration NOW OPEN! Click here to register!

Join River Action for our annual Taming of the Slough Adventure Triathlon this fall to paddle, mountain bike, and run your way to the top. This year's Taming of the Slough will take place in downtown Moline. The route takes you through the Sylvan Slough by kayak or canoe, then through one of the Quad Cities excellent single track mountain bike trails on Sylvan Island, and finishes with a run through downtown Moline.

This year we are also holding a race on an endurance route for our more seasoned racers if they so choose. It is called Going the Extra Mile and will start in Port Byron on mountain bikes hitting the trails at Dorrance Park and Illiniwek Forest Preserve before switching to a paddle at Empire Park. The paddle will first circle Campbell's Island before meeting the normal Taming of the Slough course at the Bass Street YMCA. The run portion will be identical to the extended run portion for this year's Taming course.

Compete individually or form a team to Tame the Slough!
