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.

Join us for the third annual Dragon Trails Triathlon! We are excited to invite any adventurous athletes to race this scenic and rugged sprint triathlon course. You will be challenged with a .75K (.46 mile) freshwater swim through Tommy’s Lake, a 20K (12.4 miles) of mixed terrain biking through Bald Mountain, the Polly Ann Trail, and Orion Oaks County Park, and a 5K (3.1 miles) run through the forested trails of Camp Agawam.
This event is truly one of a kind, and our race organizers are excited to host a limited number of athletes through an intimate and organized open water swimming, mountain biking, and trail running experience. While competitive, we've capped registration at 100 participants to limit chaos and congestion and ensure athlete safety.
All registrants will receive a swim cap, event shirt, pre run fuel options and on course nutrition, and drink ticket to use in our "Dragons Lair" after the race.
Maps of the 2025 Dragon Trails Triathlon are included below. 2026 courses coming soon!
