Did somebody say more cowbell?? Rumble on the Ridge is our Driftless take on the classic Backyard Ultra–Last Person Standing format. The event takes place on an old family dairy farm just 40 minutes west of Madison, WI, right in the heart of the Driftless Area. Runners compete on a 1-ish mile looped course, affectionately called “The Drifty Mile,” completing one loop every 20 minutes. Sounds easy enough… right?

To keep things interesting, we change the route every year and don’t publish details until race day. What we can tell you: the loop will be between 1.0 and 1.25 miles, it will have at least 250 feet of elevation gain, and you’ll have 20 minutes to finish each loop. The rest you’ll just have to show up to discover. Oh—and the route reverses direction every 4 hours, so you can never get too comfortable.
