Welcome to the 2018 Cohasset Triathlon. This iconic event draws one of the largest race fields in the region. Our success is based on a super strong following from our returning athletes along with our attention to detail to ensure every single athlete has a first class experience on race day..
UPDATE: on December 1, 2018, the race field filled to capacity. For athletes who did not secure a bib number in time, we highly encourage you to sign up on our wait list. We have had good success in the past accommodating most of our athletes.
Best wishes for a safe and happy Holiday.
