The B.A.A. Half Marathon begins and ends at White Stadium in Boston’s Franklin Park.
The park, one of the oldest in America, is located in Boston’s Jamaica Plain and Dorchester neighborhoods.
With a start on Pierpont Road, the course proceeds out of Franklin Park, along New Washington Street and Forest Hills Drive, and past both the Arnold Arboretum and Jamaica Pond as The Arborway becomes The Jamaicaway.
The course then passes Willow Pond and Olmsted Park, before the turn around point on The Riverway 4.75 miles into the race.
On the return, runners hug the western side of the Emerald Necklace, with Leverett Pond, and Jamaica Pond now on the left.
The race re-enters Franklin Park and loops around animal enclosures in the Franklin Park Zoo, before finishing on the track in White Stadium.
