Race Details
This is the race that started the Swimrun movement in North America. It is an incredibly diverse route with cold, salty swims and runs traversing quintessential New England island roads. Every year, the course changes depending on the tides. A swim crossing one year might be a run leg the next. You must be prepared for anything and everything. This course suits a robust, well-rounded athlete with a keen sense of adventure.
