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.

What is Swim to the Moon?
Swim to the Moon is an extraordinary open-water swimming adventure through the picturesque Hiland Chain of Lakes near Hell, Michigan. Choose your distance — .5 Mile, 1.2 Mile, 2.4 Mile, 5K, 10K or 15K — and have the time of your life swimming through Southeast Michigan’s most sublime waterways, all the while showing support for a very worthy cause: North Star Reach, a camp for children with life-threatening, serious, and chronic medical conditions.
The 5K swim starts on the shores of Patterson Lake at North Star Reach; from there, swimmers head south and east through the heavily forested Pinckney Recreation Area, passing through five lakes along the way. Scattered cottages are the only signs of civilization. The 5K will finish once they reach Halfmoon Lake Beach. 10K race participants start at Halfmoon Lake Beach, swim to the start of the 5K (where their “special needs” bags will be available), then turn around to head back to the shores of Halfmoon Lake Beach. The 15K race participants start on the shores of Patterson Lake at North Star Reach; from there, swimmers head south and east through the Hiland Chain of Lakes to Halfmoon Lake Beach where they will exit the water (where their "special needs" bags will be available), then head back to Patterson Lake Beach at North Star Reach where they will again, exit the water, access their special needs bags (if desired) and turn around to head back to Halfmoon Lake Beach for their finish.
The .5 Mile, 1.2 mile, and 2.4 Mile swims start at Halfmoon Lake Beach. All events finish at the state beach on the east shore of Halfmoon Lake.
