Rumble on the Ridge
Arena, United States • 17 May 2025
Rumble on the Ridge is an exciting endurance event inspired by the Backyard Ultra format, taking place on a scenic family dairy farm in Arena, Wisconsin. Participants will tackle a looped course, known as "The Drifty Mile," which ranges from 1 to 1.25 miles with a minimum elevation gain of 250 feet. Runners must complete each loop within 20 minutes, with the course changing direction every four hours to keep the challenge fresh. The event continues until only one runner remains who can finish the loops in the time limit. Additionally, a portion of the proceeds supports the development of the Driftless Trail.
