The 13.1-mile, rolling course combines both a looped and out-and-back route, beginning and ending near White Stadium (also known as Schoolboy Stadium) in Boston's Franklin Park. Past participants in the B.A.A. Half Marathon should note this important change. Essentially, the course has been flipped from past years. From Franklin Park, the race heads North to the Forest Hills Overpass and the Arborway, running adjacent to the Arnold Arboretum. The course turns right at Pond Street and continues North-bound onto the Jamaicaway (which becomes the Riverway), along Jamaica Pond and the other ponds and waterways that comprise Boston's Emerald Necklace. As the Riverway intersects with the Fenway, the race reverses direction with two left turns that sends runners South-bound on the Riverway.
After crossing over Huntington Avenue via overpass, there's a sharp right turn onto River Road in Brookline, followed by a sharp left turn onto Pond Ave. As the course hugs the western border of the Emerald Necklace, it turns left on Francis Parkman Drive, and then turns right on the Arborway and heads back adjacent to the Arboretum, over the Forest Hills Overpass, and into Franklin Park on Franklin Park Drive. In Franklin Park, the race turns right on Circuit Drive/N Jewish War Veterans Drive, and continues in a southward direction into the park for about a mile, before a hairpin turn reverses the course back on the same road.
The course passes the entrance/exit to the park on the left, and continues northward on Circuit Drive/N Jewish War Veterans Drive towards the Franklin Park Zoo. After a right turn on Pierpont Road, the race enters the Zoo for a quick counter-clockwise loop, and exits with a right turn onto Pierpont. Just before Pierpont intersects with Seaver Street, the course cuts across the park in a Western direction and turns right onto Playstead Road, before a finish near White Stadium. Please note that the course will remain open for two hours, 30 minutes after the start. Participants unable to complete the race within that time period will be asked to finish the race on the sidewalk. Timing will conclude 2:30:00 after the start. Go to map of the course.
