The Rock CF Thumb Coast Marathon

The Rock CF Thumb Coast Marathon, Half Marathon, and 5K is set to take place on November 2, 2025, along Michigan's scenic Thumb Coast. This event features a flat, fast course that offers breathtaking views of Lake Huron. Runners can participate in a full marathon starting in downtown Caseville, a half marathon beginning at Sleeper State Park, or a 5K loop around downtown Port Austin.

The event not only promotes fitness but also supports the Rock CF Foundation, which aids individuals living with cystic fibrosis. Participants can also opt for virtual race options, making it accessible to a wider audience. Visit the organization's website for the most recent information.
