Description
Since 1986, the iconic and classic Ann Arbor Tri has been 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, and then run the Potowatomi Trail. It’s a classic course you’ll come back to again and again.
