We preview the Zumbro Endurance Run. Even if you don't know what a Zumbro is (it's a river, and a footrace named after that river), you'll enjoy this podcast about the race in southeastern Minnesota. We visit with John Storkamp, the race director; Stephanie and Ava Hoff, a mother and her ten-year-old daughter who are both running the 17 miler; and Kurt Keiser, 50 mile men's record holder. Also, I attempt bumper music!
