Thumb Coast Ultra & Relay wouldn't be possible without our incredible volunteers. Every year, local residents, community organizations, families, and runners' friends come together to staff aid stations, cheer along the course, and help runners achieve goals they've spent months preparing for. We love seeing the Harbor Beach and Thumb communities come together to showcase the hospitality that makes this region so special.
