The iconic and classic Ann Arbor Tri continues the tradition with the inclusion of a mini-sprint and the WolverineMan Collegiate Conference Tri.

The Ann Arbor Triathlon is held in the Pinckney Recreation Area at Halfmoon Lake, one of the largest state parks in all of Michigan. You’ll swim the open waters of Halfmoon, bike the rolling paved country roads of the surrounding rural area, then run the 5-mile classic Poto Trail. It’s a classic course you’ll come back to again and again.

The WolverineMan Collegiate Conference Race will be held alongside the Ann Arbor Triathlon.  Cheer on the collegiates as they lead off the race from various collegiate tri teams including Michigan State University, Northwestern University, Miami of Ohio, University of Michigan (host), and many others.

Support our featured charity, Make-A-Wish by joining DREAM TEAM. DREAM TEAM is a dedicated group of individuals coming together to form a TEAM! The DREAM TEAM participates in endurance events such as triathlons, marathons, 5ks, 10k, etc. and raise funds for Make-A-Wish Michigan, helping grant wishes to Michigan children with a critical illness. The Dream Team believes wish kids deserve to have a wish granted…but there are costs associated with granting wishes. By raising funds for Make-A-Wish Michigan and committing to participate in the race, we can help grant wishes!

>> 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

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 SUP company, Red Star Board Company. We’re very grateful to have Red Star as part of Epic team.


>> USA Triathlon

Because our triathlons are sanctioned by USA Triathlon (USAT), we follow their wetsuit rules. Competitors may wear wetsuits if the water temperature is 78 degrees or lower. USAT rules also state that if the water temperature is between 78.1 – 83.9 degrees, competitors may wear wetsuits but will not be eligible for awards.
