Caseville, Michigan (United States of America) - "Thumb Coast Ultra & Relay". Beat the sunset in Caseville, Michigan! Michigan’s Thumb is full of quiet roads, big skies, and unexpected beauty, and the 2026 Thumb Coast Ultra & Relay is your chance to run from one Great Lake to another. On Saturday, April 25, take on a point-to-point 50 Mile from Lake Huron in Harbor Beach to Saginaw Bay in Caseville, a fast and scenic 50K out-and-back, or rally your crew for the 50 Mile Relay and chase the sun across the Thumb. Can you beat sunset to the finish? This route follows mostly flat dirt roads through open farmland and lakeshore views, with generous cutoff times and fully stocked aid stations.
