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.
