The Dirty Mitten is a great early fall race and a proud member of the Boundless RR Co. Grand Prix and a premier event for the I Love Gravel Racing Series . The race starts and ends at the YMCA’s Camp Manitou-Lin in Middleville, MI. Situated halfway between Grand Rapids and Kalamazoo, it’s a convenient venue for just about all of West Michigan so you have no excuse not to come out!
