UP Health System Great Bear Chase

The UP Health System Great Bear Chase, held on March 7, 2026, in Calumet, MI, offers an unparalleled winter endurance challenge across distances of 53K, 24K, 20K, 10K, and 5K. While primarily celebrated as a premier cross-country ski marathon, the event's renowned course and community spirit translate to an equally formidable experience for any athlete seeking a challenging trek through Michigan's rugged Keweenaw Peninsula. Expect typical race day conditions around 10-32°F, with only a 7% chance of precipitation, creating a crisp, invigorating atmosphere.

The scenic course winds through the pristine, snow-laden Swedetown Trails and Michigan Tech Trails, known for their varied terrain and elevation changes. Runners on the longer distances will navigate wide opening sections, transitioning to narrower 12-20 foot trails that demand focus and agility, all without encountering any road crossings. Sections like Mama Bear, Papa Bear, and Baby Bear offer distinct challenges amidst the region's abundant annual snowfall, which regularly exceeds 200 inches, ensuring a truly immersive winter experience. Aid stations strategically placed every 2 km will keep participants fueled with water, Gu Hydration drinks, bananas, and Gu energy gel.

Since its inception in 1981, the Great Bear Chase has cultivated a reputation for its small-town charm and exceptional hospitality, drawing participants from across the globe. This volunteer-powered event, a major fundraiser for the Swedetown Trails, prides itself on being "built by racers for racers." The atmosphere is described as friendly and laid-back, featuring a post-race pasty luncheon, unique local artisan awards, and a pervasive sense of community that makes the arduous journey through the winter wonderland truly special. The race starts near the welcoming snowmobile groomer building, which also serves as a warming area, just a short walk from the finish line.
