2015 Boston Light Swim ~ August 15, 2015 7:00AM

The Boston Light Swim has been a local tradition since 1907, the Boston Light Swim is the oldest open-water swim marathon in the United States of America. Participants begin the race in the water at Boston Light on Little Brewster and continue past George’s Island and Rainsford Island, under the Long Island Bridge, around Thompson’s Island, finishing 8 miles later at the L Street Bathhouse in South Boston.

This swim is perfect for individuals who would like to try a cold water ocean swim. Many swimmers in the past have used this swim to prepare for an English Channel crossing. The 8 mile swim is a non-wet suit event.
