The Experience

Starting and finishing at the Tree House Brewing Company in South Deerfield, Massachusetts, the Tree House Half Marathon has quickly become a destination race. In its recent editions, the event drew nearly 2,000 runners from 32 states, with about a quarter returning each year—a sign of its growing appeal.

The typical winning time hovers around 66 minutes, hinting at a fast course that attracts competitive runners. But the real draw is the post-race celebration at one of New England's most celebrated craft breweries, where the finish line party is as much a tradition as the race itself. With its combination of a spirited field, beautiful Pioneer Valley setting, and world-class beer, this half marathon has carved out a loyal following.
