Bay City, MI

Bay City sits on the Saginaw River in Michigan's Thumb region where the terrain flattens out toward Lake Huron—the Driathlon and Bay City Memorial Run Events use the riverbank and local parks as their backbone. Cyclists dominate here: the Frankenmuth Fondo Ride and J.P. Wanderwheels Thumbs Up! tap into the quiet rural roads through farm country, while serious gravel riders tackle Michigan's Coast to Coast Gravel Grinder 204-Miler for genuine distance and surface variety across the state. Running is mostly flat park loops and river paths; cycling is the draw.
