Thumb Coast Ultra

The Thumb Coast Ultra is a spring ultra marathon held in Michigan, featuring 50-mile, 50K, and 50-mile relay options. The race takes place in late April, starting in Harbor Beach and finishing in Caseville, running along Michigan’s Thumb region from Lake Huron to Saginaw Bay. The course primarily follows dirt roads and offers a scenic route through this hidden gem of Michigan.

The event welcomes runners of all levels, from beginners to seasoned ultramarathoners, with well-marked trails and ample aid stations. A unique challenge is to finish the 50-mile race before sunset, with special prizes for those who "beat the sun.". Visit the organization's website for the most recent information.
