Prepare for an unparalleled wilderness challenge at the 16th annual Stubborn Mule Adventure Race, returning to the rugged north woods of Cable, Wisconsin, on June 27, 2026. Offering 5-hour, 12-hour, and 24-hour race options, this event caters to both newcomers eager for a "choose-your-own adventure" style introduction and seasoned veterans seeking demanding navigation and route choices. Typical race day conditions in late June bring comfortable highs around 75°F and lows around 53°F, with a modest 17% chance of precipitation, creating an ideal environment for endurance sports.

The professionally designed course by 180 Adventure promises an epic journey across diverse disciplines: trekking through thick underbrush and bogs, exhilarating mountain biking on fast gravel and challenging doubletrack, and serene paddling on the region's famous quiet waters (watercraft are provided). Participants will hone navigation skills amidst the distinct topography and breathtaking beauty of northern Wisconsin's wilderness, where encounters with local wildlife like deer, bears, and porcupines add to the unforgettable experience. While logistics for the 24-hour race are unsupported, racers can look forward to a delicious post-race meal and a lively camaraderie that defines this top-tier Midwest adventure race. The exact "super secret" start location is revealed one week prior, ensuring an element of mystery for your next great adventure.
