Healthy Rivers Partnership 


The Healthy Rivers Partnership (HRP) is a nonprofit organization dedicated to connecting people to their rivers and rivers to their communities. Formed from a shared commitment to water resources, river clean ups and watershed education, the organization does river clean-ups, river education, riparian restoration, on-the-water field trips and provides safety boats and checkpoint coordination for the Missouri River MR340 race.  




Rivermiles has been promoting Missouri River awareness since 2006 with the inaugural running of the Missouri River 340.  Rivermiles believes that the best way to protect our river resources is through participation, inviting paddlers and their families to experience the rivers through the adventure of canoe racing.   


These events create lifelong fans and stewards of the rivers and link the communities in the watershed in ways they've never considered.   The MR340 is known internationally as the world's longest non-stop river race and has attracted paddlers from Japan, Malaysia, Canada, Australia, Denmark and the United Kingdom.
