Triathletes throughout Michigan have long considered the Island Lake State Recreation Area, home of the Island Lake Triathlon, an epic training destination, ideal for any athlete preparing for a multisport event. Set within a 4,000-acre park in Livingston County that offers an “up north” experience without leaving southeast Michigan. The terrain is a mixture of open brush land to mature hardwood forest, with some pockets of open meadows mixed in with a paved road of rolling hills weaving throughout. You’ll swim the clear waters of Kent Lake, bike the park’s rolling, tree-lined hills, then run the panoramic final leg towards the lakeside finish line!
