What's New

Welcome to the 2014 Marshfield-Duxbury Triathlon. We are excited to stage a terrific mid-summer at Duxbury Beach. Special thanks to the Town of Duxbury, Town of Marshfield, and the Duxbury Beach Reservation for their continued support in this great event.

Based on feedback from our returning athletes, the finish line will be moved to the beach this year. This improvement will offer a quick sprint to the finish line and a fun post-race atmosphere.
