Welcome to UltraTrax Ann Arbor. On June 5, 2027, you’ll take on a full day of movement, challenge, and time on the trails at Mt. Brighton. For the first time, UltraTrax is heading to Michigan. This is one of our more accessible mountain courses, combining open, rolling terrain with just enough elevation to keep things interesting. The first half of the loop moves across the resort’s former golf course, where wide grassy trails wind through fields and seasonal wildflowers. From there, the course heads back toward the lodge before taking on Mt. Brighton itself for a taste of climbing and a rewarding finish. Whether you’re here to walk 7 miles or push all the way to 28, the challenge is yours to define. 10 hours. One 7-mile loop. Four distances. How far will you go? Complete your goal within the 10-hour event window. Want another layer of challenge? Take it on with a 10, 20, or 35 lb. ruck or weighted vest. The course will be clearly marked from start to finish, with well-stocked aid stations positioned along the route to keep you fueled and moving. Trek Day Saturday, June 5, 2027 Mt. Brighton, Brighton, MI The start line is open between 7am-10am and is divided into corrals based on distance. 28 milers get started at 7am, 21 milers at 7:45am, 14 milers at 8:30am, and 7 milers at 9:15am. UltraTrax is not a race, but it is a timed endurance event. You’ll have up to 10 hours to complete your chosen distance. Move at your pace. Take breaks when you need them. Then keep going. Bib Pickup Your bib may be mailed to you in advance or picked up on event morning. Participants registering after May 10, 2027 must pick up their bib in person. Taking on the Ruck Challenge? If you registered for a weighted division, you’ll need to bring your own ruck, backpack, or weighted vest. Your pack will be weighed before you begin. Everything in the pack counts toward your required weight except perishable food and drinks. What’s Waiting at the Finish Finishers will receive: A custom UltraTrax finisher medal (Grey Wolf Medal for 28 and 21 milers, Trail Wolf Medal for 14 and 7 milers) UltraTrax event T-shirt UltraTrax patch Additional swag for weighted divisions After your trek, stick around and enjoy the Base Camp atmosphere at Mt. Brighton. Recover, refuel, and celebrate the miles with other participants. Friends and family are welcome to join you at Base Camp. What to Expect at Ann Arbor An Accessible Mountain Experience The first half of the course winds through the resort’s former golf course on wide grassy trails surrounded by open terrain and wildflowers. From there, you’ll make your way back toward the lodge and onto Mt. Brighton itself. The climbs add just enough elevation to break up the miles without the sustained ascents found at some of our more demanding mountain venues. A Challenge You Choose There is no single definition of success at UltraTrax. Walk your first 7 miles, chase 28, or add weight and see what you can carry. Support Along the Way Expect a well-marked course, stocked aid stations, event staff, and a community of people working toward their own goals alongside you. Parking Complimentary onsite parking will be available at Mt. Brighton. More detailed arrival, parking, course, and event-day information will be sent as Trek Day gets closer. Move With Purpose UltraTrax is all about spending more time outside, moving farther than you thought you could, and helping protect the places that make those experiences possible. A portion of UltraTrax proceeds supports efforts to protect and preserve the outdoor spaces we depend on. You’re officially part of the pack! We’ll see you in Ann Arbor. --- Source: [https://runthis.run/event/rs-215649-ultratrax-annarbor](https://runthis.run/event/rs-215649-ultratrax-annarbor) — data from Run This (runthis.run).
