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. The 10 mile route goes east of the camp.

While we started with Grand Rapids Triathlon and Michigan Titanium, we have since expanded into the gravel scene. We now produced not only three gravel bike events (Waterloo G+G, The Dirty Mitten Gravel Bike Race & Rode To Hell), but we also have two of only a few gravel triathlons in the country: Ugly Dog Gravel Triathlon and The Dirty Mitten. If trail running is your thing, we also offer the Brainy Day Trail Run.
NEW FOR 2023: Join us as Gran Fondo returns as the Grand Rapids Gran Fondo, now a Tris4Health cycling event!
