What's New

Welcome to the 2017 Cohasset Triathlon! We are humbled by the incredible support from the community, athletes, sponsors, and our phenomenal volunteers.

On Sunday, June 25, 2017 - take part in one of the largest race fields in the region. Online registration will open on Thursday, December 1st at 8:00 am.

Please join our mailing list to get the very latest updates and reminders about the opening of registration as this event historically sells out very quickly.

Thank you,

Bill Burnett
