The Dirty Mitten Trail Run

Nestled in the heart of Middleville, Michigan, is the beautiful YMCA Camp Manitou Lin. It is one of the best venues in the area for tri-sport. A beautiful sandy beach start from the shores of Barlow Lake, to a breathtaking ride through the rolling hills of the surrounding countryside to an out & back run along the lakeshore, this is a must-do event for every triathlete. Positioned as a boutique event, entry is limited so we can offer great SWAG for everyone, generous transition space and cash prizes not only for the winners but also for 2 lucky random drawings. And the proceeds from this event supports local nonprofit myTEAM TRIUMPH West Michigan Chapter. Join us as we celebrate ability together! We remain committed to create a VIP experience just for YOU! Watch this spot or follow us on Facebook for the latest updates!
