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 family dairy farm in Arena, Wisconsin. Participants navigate a looped course, known as "The Drifty Mile," which varies between 1 to 1.25 miles with a minimum elevation gain of 250 feet. Runners have 20 minutes to complete each loop, with the course changing direction every four hours to keep the challenge fresh. The event continues until only one runner remains who can complete the laps within the time limit. All proceeds support the development of the Driftless Trail, promoting outdoor activities in the area. Visit the organization's website for the most recent information.
