Half Marathon-by-the-Sea

2026 Tree House Brewing Company Half Marathon
Sunday, September 13, 2026 — South Deerfield
Yes, the date is the same as the Half Marathon-by-the-Sea — a tough choice! This race starts and finishes at the Tree House Brewing Company, one of the most beloved breweries in the Northeast. The course runs through the Pioneer Valley, with gentle terrain and plenty of fall previews. After you cross the finish line, the reward is a well-earned beer. It’s a Solid Pick with a fun, social vibe.
Town and Country Half Marathon & 5K
Sunday, June 28, 2026 — Newburyport
