Every July, more than 500 paddlers push off from Kansas City down 340 miles of massive Missouri River current, paddling day and night across the state in one of the world’s longest nonstop river races. This is the MR 340, an event of endurance, suffering and transformation. From solo racers chasing records to 10-person canoes grinding it out over four brutal days, every paddler faces the same river. In this episode, we sit down with Kate Mansker, a racer from the very first MR 340 in 2006 who still holds course records, and Steve Schnarr, the race director who steers the chaos behind the scenes. Together, they chart the evolution of the race, the legends it’s created, and what it takes to avoid the Reaper.

Katie Veteto is a river guide with quiet calculated confidence and a sharp eye for water. Within a few years she was navigating one of the most difficult crafts on the river—the massive sweep boat. NRS's new film Driving Sweep, directed by River Radius Contributing Host Greg Cairns, follows her journey of learning, doubt, and determination as she takes on a role historically dominated by men. Through her story, the film offers a powerful reflection on resilience, mentorship, and making space in wild places.

GUESTS

Katie Veteto
Katie Veteto was born in Southern Utah, raised in the Missoula Valley, and now spends her time in Missoula, MT and Salmon, ID. She grew up seeing the rivers of the West through the joyful lens of community and recreation and continues to guide on rivers in Montana and Idaho. Katie is an elementary school teacher. During Katies time off, you’ll find her romping in the woods with her dog Tuck, swing dancing, knitting hats, writing, or bumping around on a bike. In the Summer you’ll find her somewhere on the Middle Fork of the Salmon.

This is the 3rd and last episode about the Tijuana River. The Tijuana River is a story of trade, immigration and international borders. This is a river that flows across the US Mexico border and carries pollution and sewage. Our guest is Dr Maria-Elana Giner; she served as commissioner of the International Boundary and Water Commission and upon request of President Trump, she resigned from this position in April of 2025. In this 3rd episode we look for solutions to this epic challenge for the US and Mexico.

Many of our favorite rivers run through public land, land that is owned and managed by the Federal Government, and so therefore owned by the citizens of the United States. There is renewed chatter in Washington DC suggesting that major sales of public lands can create significant revenue for the Federal Government. This episode hosts experts on this topic from the Idaho Outfitters & Guides Association, and the Greater Yellowstone Coalition to learn more about who wants this, why this is being considered, what are the benefits, and how listeners can engage in the process.

Do you ever wonder if bots are being used to acquire river permits during the annual cancellation lotteries each year? So do we. So we built a bot to see if it works to secure permits. And we tried talking with rec dot gov to get their input. Check out this episode for a tour of bots, permits, bureaucracy and access to public rivers.

The Tijuana Rivers courses through the City of Tijuana Mexico where 2 million people live. Several hundred thousand homes in Tijuana are not connected to the city sewage system and this leads to significant pollution of the Tijuana River. And because the city of Tijuana butts right up to the US Mexico border, the path of the river sewage and the responsibility for managing is not always clear. This episode goes into Tijuana to learn more about why the pollution exists, where it comes from and the status of various infrastructure tools that manage the pollution.
