As a participant in the 2012 Boston Triathlon, you will swim in the clean, warm waters of Dorchester Bay, bike on flat, car-free Day Boulevard, and run along the shore to Pleasure Bay. The finish is on the beach, in one of the most stunning locations imaginable. Following the race, you can celebrate with friends and family at the post-race party behind the famous L Street Bathhouse with a cold beer from Harpoon Brewery – our Official Beer Sponsor!

The course is spectator-friendly and easy to get to. Logistics are a breeze, parking is plentiful, and the vibe is awesome.

Registration is open and the race field is filling quickly. Sign up soon!
