UltraTrax Wachusett

About the Event

A summit-driven grind up Wachusett Mountain where steady climbs, rocky pitches, and winding forest trails test your legs and reward your effort. The route traverses Wachusett’s ski slopes and wooded single-track, climbing through pine and hardwood forest before breaking onto exposed upper mountain terrain with sweeping views across Central Massachusetts and, on clear days, all the way to Boston’s skyline.  Push your pace. Carry your weight. Move with the pack.

 
Choose your distance: 7, 14, 21, or 28 miles, and complete in 10 hours to earn the coveted UltraTrax Grey Wolf Medal. Toss on a 10, 20, or 35-lb weighted vest or ruck and unlock bonus finisher swag + serious bragging rights. The course will be extremely well marked with a fun post-trek party for everyone to enjoy!

Trek Day Information

UltraTrax Wachusett kicks off at 7am on August 30, 2026. The starting line will be open from 7am to 10am with the post-trek party starting at 11am. It is not a race, but it is a timed event and walkers will have 10 hours to complete the course. Bibs can be mailed or picked up the morning of the event. **IF YOU REGISTER AFTER 8/15/26, BIBS MUST BE PICKED UP IN PERSON. A friend or relative can pick up a bib if you can't attend. Complimentary parking is available onsite. Finishers will receive a custom t-shirt and velcro patch. Level 3 and 4 participants will also qualify to earn our coveted UltraTrax Grey Wolf medal. Refreshments and food will be available after the race.
