The Experience

The UltraTrax Wachusett event is a true mountain test, taking runners on a demanding loop up and around Wachusett Mountain. The course is a rugged journey, traversing ski slopes and single-track trails that wind through pine and hardwood forests. As participants climb higher, the terrain becomes more exposed, revealing sweeping vistas across Central Massachusetts, with the Boston skyline visible on exceptionally clear days.

This is not a road race; expect steady climbs and rocky pitches that challenge your legs and resolve. Runners can choose from multiple distances, including 7, 14, 21, or 28 miles, with a generous 10-hour time limit for all. For an added layer of difficulty and bragging rights, participants can opt to carry a weighted vest or ruck. The event, first run in 2026, is known for its extremely well-marked trails and offers a unique challenge for those seeking a summit-driven grind.

Race-provided description

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.
