On Halloween morning, the Stony Brook Fire Department invites runners and walkers of all ages to participate in the SBFD Monster Dash 5K Race and Fun Walk. Scheduled for Saturday, October 31, 2026, at 9:00 AM with a staggered start time for both events, this festive race promises an exciting blend of community spirit and spooky fun. Participants can choose between the competitive 5K run or a more relaxed 1-mile fun walk. Both routes wind through the charming streets of Stony Brook, offering runners scenic views of historic buildings and vibrant fall foliage as they make their way around town. The atmosphere is electric with enthusiastic supporters cheering along the course and local vendors providing refreshments. Costumes are highly encouraged for both participants and spectators, transforming this race into a thrilling costume parade where creativity knows no bounds. Runners can expect to see everything from elaborate monster outfits to clever firefighter disguises as they cross the finish line. For those who register early by October 1st, there's an additional incentive: guaranteed t-shirts. The event is part of the larger 5th Division Mutual Aid Race Series, which includes previous races such as the Run For Heroes and Terryville FD Stop, Drop & Run events earlier in the year. This series not only promotes community health but also raises awareness for local fire departments' efforts to protect their communities throughout Suffolk County. As runners cross the finish line at 147 Main Street, they'll be greeted by a lively celebration complete with awards and prizes for top finishers as well as a sense of camaraderie among participants. The Stony Brook Fire Department is committed to making this event an unforgettable experience that brings together families and friends in support of local heroes.
