From the organizers
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.
