The 2025 Dirty Mitten Gravel Triathlon

Dirtfest Weekend presented by PTSportsPRO returns in 2025 with more ways to GET DIRTY!

The Dirty Mitten Gravel Triathlon in 2025 is set to host the fourth annual Gravel Triathlon World Championship (of the Universe)!

The race takes place at the YMCA’s Camp Manitou-Lin in the aptly named 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! It features Sprint(ish) and Olympic(ish) distance triathlons along with duathlons, aquabikes, and relays for those of you who might not want to participate in all three disciplines.

Your day will start on the shores of Lake Barlow with a one or two loop swim. Transition is a short run away before heading out onto the beautiful gravel roads of Barry County. The sprint course will feature an out and back on Bowens Mill Road while the Olympic course will work its way south and east, exploring some of the best gravel roads Michigan has to offer. Once you’re back at camp, a quick change of your shoes and you’ll be off onto the trails of Camp Manitou-Lin for the trail/cross country run portion.

Forget pavement and skinny tires – get ready to ride gravel and run trails!

This race is part of a three-part event weekend, with a 5K trail run kicking off Saturday morning before the gravel bike race. Race all three events to be part of the GreenLeaf Trust Trifecta or race both Saturday and Sunday to earn The Dirty Double!
