UltraTrax Wachusett

Event Overview

UltraTrax Wachusett is a timed mountain event taking place in Princeton, Massachusetts. This summit-driven course traverses the terrain of Wachusett Mountain, utilizing a loop system that covers ski slopes, wooded single-track trails, and rocky pitches. The route winds through pine and hardwood forests before reaching exposed upper mountain sections. On clear days, the summit offers views across Central Massachusetts and toward the Boston skyline.

Participants can choose from four different distances based on the number of completed loops:

• 7 miles (one full loop)
• 14 miles (two full loops)
• 21 miles (three full loops)
• 28 miles (four full loops)
