The 2012 Cohasset Triathlon race field sold out in record time - one of the fastest sell outs for a sprint race in the country. We are humbled by the amazing support and following. Thank you very much.

For those athletes who were not able to secure a number, please sign up on our wait list here. We will notify you if and when a number becomes available.

Please consider racing in one of our other great events listed on the left side of this page.

Finally, we are proud to support the Juvenile Diabetes Research Foundation. Over the last five years, the Cohasset Triathlon has raised $765,000 to help find a cure for Type 1 diabetes. This event also supports a host of local organizations including the Cohasset Food Pantry and the Sandy Beach Association.
