ABOUT SwimRun Boston

ethos, the organizer of the Boston Triathlon and the Lobsterman Triathlon, has joined forces with SwimRun USA to bring the sport of swimrun to Boston.

SwimRun Boston Harbor Islands will take place on Saturday, June 16, 2018. Not for the faint of heart, participants will compete in teams of two, remaining together as they run across each island before swimming to the next island, repeating the process until they reach the finish line and post-race party on Spectacle Island.

About SwimRun USA

After being inspired by ÖTILLÖ, the iconic island to island swimrun in Sweden’s Stockholm Archipelago, two long standing multisport event producers, Jeff Cole and Lars Finanger, teamed up to bring the sport to North American soil with the 2016 Casco Bay Islands SwimRun outside of Portland, Maine. Now entering its third year, the aim remains the same; to offer athletes best-in-class epic races in unique places. SwimRun Casco Bay Islands and now SwimRun Boston are the only events in the US remaining true to the spirit of island-to-island racing. SwimRun Casco Bay Islands is an official MERIT Race for ÖTILLÖ SwimRun World Championship ranking points.
