SWIM

Racers will be challenged by the Altantic Ocean’s open water,  changing currents and tides as they make their way throughout Boston Harbor.

RUN

After long stretches in the water, racers will be greeted by a mixture of overland terrain ranging from well manicured trails to craggy rock and everything in between.
