World’s Longest Non-stop Canoe/Kayak Race Returns to Missouri July 12 – 15

650 paddlers will race in the Missouri American Water MR340 to support river preservation

On Tuesday, July 12, roughly 650 paddlers will launch from Kaw Point Park in Kansas City to begin the 17th Annual Missouri American Water Missouri River 340 (MR340) river race. Participants will paddle 340 miles across the state in this endurance race with the goal of crossing the finish line in St. Charles. 

The Missouri American Water MR340 brings awareness to the importance of our rivers, which serve as a reliable source of drinking water for millions of Missourians. 

The MR340 race combines extreme sports and environmental stewardship. Race proceeds benefit two environmental stewardship and education organizations: Missouri River Relief and the Lewis & Clark Boat House & Museum. The race includes solo and team kayaks, canoes, standup paddleboards, pedal drive boats and rowing craft, all human-powered. The race is nonstop, meaning participants may choose to paddle all day and night.
