UltraTrax Wachusett

You’re In. Welcome to UltraTrax Wachusett.

Get ready for a full day of movement, challenge, and time on the trails at Wachusett Mountain.

Your course winds through Wachusett’s wooded mountain terrain, combining steady climbs, rocky stretches, ski slopes, and forest trails through pine and hardwood forest. This is a course that makes you work for every mile, with enough elevation and variety to keep things interesting from your first loop to your last.

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.

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 the bib-mailing cutoff 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. Food and drinks will be available for purchase, with space to recover, refuel, and celebrate with other participants.

Friends and family are welcome to join you at Base Camp.

What to Expect at Wachusett

A Mountain Course That Makes You Earn It Wachusett packs a lot into seven miles. Expect sustained climbing, rolling mountain terrain, rocky sections, wooded trails, and stretches across the ski area that will keep your legs working throughout the loop.

New Views Every Loop Move through dense New England forest, open ski terrain, and changing elevation as you make your way around the mountain. Wachusett delivers the kind of course where each completed loop feels earned.

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 parking is available onsite at Wachusett Mountain.

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 land conservation and organizations working to protect and maintain the trails and outdoor spaces we depend on.

You’re officially part of the pack! We’ll see you at Wachusett.
