Sharks in Boston Harbor? Bostonians call them “Shaaahks”! Imagine swimming across Boston Harbor from Portside at East Pier in east Boston to the swim finish at the John Joseph Moakley US Federal Courthouse at Fan Pier in South Boston. You can do this! We are thrilled to bring our popular open water swim series to Boston. The 1500 meter competitive swim will have downtown Boston for a backdrop as athletes navigate across the channel to a thrilling finish. The Coast Guard will stop all boat traffic in and out of the channel during this event. Water taxis will transport swimmers from the finish line to the start of the swim. The event is limited to 800 participants.
