Epic Races' Island Lake Triathlon, Duathlon, Aquabike

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!
