Registration for the 2019 Lobsterman Triathlon is NOW OPEN!


RACE DAY is Saturday, September 7th, 2019. 

LOBSTER BAKE INFO: Please note that your race registration does not include a ticket to the lobster bake. Tickets are $35 and can be purchased through Active. 

Registration changes, and other edits will not be accepted via email after September 1st.  Edits such as changing categories, updating information such as date of birth, etc., can be made in person after September 10 at one of the three scheduled race packet pickups. There are no deferrals after September 1st.

We strive to provide everyone their requested t-shirt size, but they are ordered weeks in advance.  If you register after August 11,  we cannot guarantee your requested size will be available on race day. After packet pickup closes on race morning, you can try to exchange your shirt for a different size with what is leftover.  Thank you for understanding.

Race Start is 8:30 AM
