The 15th Annual Nantucket Half Marathon!

Sunday, October 11th, 2026 at 8:00 am

The Nantucket Half Marathon is one of the most scenic half marathon courses on the East Coast! Runners' World recognized the Nantucket Half Marathon as one of the nation's top ten beach town races! Set on iconic Nantucket Island, the course travels through sandy beach roads, bike paths, lightly traveled neighborhood streets, a few patches of sand, and features incredible ocean views. The 2025 race was challenging with high wind and an impending storm. The route begins and ends at historic Bartlett's Farm and highlights the Nantucket Land Bank's Smooth Hummocks Coastal Preserve. The Preserve is a globally rare sand plain grassland ecosystem. There is also a free kids fun run! Each kid gets a treasured Bartlett's Farm pumpkin! There will not be a Quarter Marathon Option this year, so start training- you will have to run the entire course! This is one of the best half marathon's in the country and it will sell out! Register today and enjoy a terrific day on Nantucket. Race

REGISTRATION FEES ARE NON-REFUNDABLE. Last year we sold out on August 1st so register early.
