Race Info
Tree House Brewing Company hosts its half marathon each September at its South Deerfield campus, neighboring Mount Sugarloaf in western Massachusetts. The course winds through the surrounding hills before returning to the taproom, where finishers get two drink tickets. The race launched in 2023 and returns for its fourth running on September 13, 2026, managed in partnership with DMSE Sports. The brewery closes to the public on race day; entry is limited to registered runners and ticket-holding spectators. Source
