The Boston Light Swim course
A point-to-point swim through Boston Harbor. Swimmers start at the Boston Light on Little Brewster Island and come ashore in South Boston (the L Street Bathhouse / Curley Community Center at M Street Beach). Swimmers motor out to the start from the Boston Harbor Yacht Club.
Race-day conditions
The organizer describes it as a non-wetsuit swim.
What to train for
Build toward several continuous swims of 3 to 4 hours in cool water without a wetsuit, and practice feeding from a boat. Work on steady pacing, since harbor tides and chop can stretch the swim.
