ILT Finish Line Image

Description of 2021 Event
Triathletes throughout Michigan have long considered 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, then join in the post-race festivities including the best recovery meal and beer tent ever!


Remember when we did things like that?


We are proud and excited to announce that we will be Samuel Adam’s beer for participants 21 and older at the finish line of the Island Lake Triathlon!

>> Wetsuit Rule/Rental

USAT Rule 4.4 Wet suits. Each age group participant shall be permitted to wear a wet suit without penalty in any event sanctioned by USA Triathlon up to and including a water temperature of 78 degrees Fahrenheit. When the water temperature is greater than 78 degrees, but less than 84 degrees Fahrenheit, age group participants may wear a wet suit at their own discretion, provided however that participants who wear a wet suit within this temperature range shall not be eligible for prizes or awards. Age group participants shall not wear wet suits in water temperatures equal to or greater than 84 degrees Fahrenheit. The wetsuit policy for elite athletes shall be determined by the USAT Athletes Advisory Council. The AAC has set the wetsuit maximum temperature for elite athletes at 68 degrees for swim distances less than 3000 meters and 71.6 degrees for distances of 3000 meters or greater. Any swimmer wearing a wetsuit with a thickness measured in any part greater than 5 millimeters shall be disqualified.

>> Water Safety

Wave Starts
The Olympic and sprint distance events will be wave starts organized by age and gender.

The Time-Trial Swim Start
The mini-sprint is a time trial swim start.  What does that mean? The swimmers line up on the beach and, at the race starter’s signal, enter the water individually at short intervals (usually three to five seconds). This is an alternative to the traditional wave start where a large group starts all at once.

Epic Lifeguard Image


Every member of the Epic Lifeguard Team has American Red Cross Waterfront Lifeguarding Certification in addition to basic American Red Cross Lifeguarding Certification. This means that our guards have all taken and passed an additional course in which they received training in the knowledge and skills needed to prevent and respond to emergencies in non-surf, open-water areas. Our superbly trained lifeguards are yet another reason our races are so Epic! Our lifeguards are also able to keep our swimmers safe thanks to our official kayak sponsor, Heavner Nature Connection Canoe & Kayak Rental. We’re very grateful to have Heavner as part of our Epic team.
