The Dirty Mitten gravel bike race is michigan’s newest gravel event and a great early fall race.

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!

DISTANCES

We offer 10, 28 and 50 mile courses for riders of all levels. See our course map for maps and links. Both the longer routes go west of the camp and are completely different than the Sunday gravel triathlon bike courses.
