NOTE: As of 2018 the course has been slightly modified – there are now just two turn buoys instead of three.
The course is a one-mile loop consisting of three legs around two large tetrahedron orange buoys. Three smaller cylindrical buoys are on the longer leg. Click on map for a larger image.
Please see our Sighting page which offers in-the-water perspectives of what to swim towards at the start of each leg of the course.
Registration is by the Arthur Fiedler head statue which is not far from the Hatch Shell on the Esplanade. Volunteers will greet people crossing either the Hatch Shell / Arthur Fiedler footbridge or the foot bridge by the Charles/MGH T station. The nearest T station is the Charles/MGH stop on the Red Line. Nearest parking is in the Boston Common Garage.
