The Missouri American Water MR340 is a true community event – a community created by the river. To witness the determination of the racers, the grit of the ground crews and the hospitality of the volunteers is a truly inspiring thing. The race is hosted by Missouri River Relief, a nonprofit dedicated to connecting people to the Missouri River through stewardship, education and recreation. We are so proud to be carrying the tradition of this world-class race. Special thanks to Missouri American Water for being our title sponsor of the race.

The race goes 24-hours a day, with racers stopping at boat ramps along the way to resupply or rest, often with “Ground Crews” of family or friends that follow along the race. There are 5 checkpoints where racers must meet the cutoff time or be disqualified from the race.
