Get ready for an unforgettable adventure at the Thumb Coast Ultra & Relay, hosted by Trivium Racing on Saturday, April 25, 2026, in the picturesque town of Caseville, Huron, Michigan. This unique race invites participants to challenge themselves as they run from sunrise to sunset, traversing a stunning route that connects the serene shores of Lake Huron to Saginaw Bay. With race distances of 50 miles and a 50-kilometer out-and-back course, both seasoned veterans and first-time racers can test their limits on mostly dirt and unimproved roads, featuring minimal elevation gain of just 500 feet for the 50-mile race and 300 feet for the 50-kilometer option.

The Thumb Coast Ultra promises an exhilarating experience, complete with generous cutoff times and special finishers' prizes for those who can "beat the sun." Participants will enjoy well-marked courses and fully stocked aid stations along the way. Beyond the race, the Thumb area boasts a wealth of attractions, including charming accommodations, delicious dining options, and family-friendly activities. Join us for a day of excitement, camaraderie, and the chance to embrace the beauty of Michigan’s hidden gem!
