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! Island Lake Tri features 7 different events: Olympic Triathlon — 1500 meter swim, 24-mile bike, 6.2-mile run Sprint Triathlon — 750-meter swim (30 lengths in a standard metric pool), 12-mile bike ride, 3.1-mile run Super Sprint (formerly Mini-Sprint) Triathlon — 400-meter swim (16 lengths in a standard metric pool), 12-mile bike ride, 1.5-mile run Olympic Aquabike (swim bike done) — 1500 meter swim, 24-mile bike ride Sprint Duathlon (run bike run) — 1.5-mile run, 12-mile bike ride, 3.1-mile run Olympic Relay — team up with one or two friends to complete our Olympic Triathlon together Sprint Relay — team up with one or two friends to complete our Sprint Triathlon together
