RACE DAY is Saturday, September 9th, 2018. 

Registration changes, deferral requests, or other edits will not be accepted via email after September 2nd.  Edits such as changing categories, updating information such as date of birth, etc., can be made in person after September 2nd at one of the three scheduled race packet pickups.

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.

LOOKING FOR INSPIRATION? Consider joining the LobsterJam Wave, which raises money for cancer research in Maine.

The second annual LobsterJAM Olympic Triathlon Aquabike & Relays is a unique, less competitive event for athletes who want to give back to the community and raise funds for charitable partners in Maine. Participants will compete together in a smaller field of athletes, and have special exclusive waves. Each athlete will be required to fundraise a minimum of $100.

Registration for LobsterJAM will open in late October.
