Course Description and Overview - Boston Half Marathon
The 2025 Boston Half, formerly known as the B.A.A. Half Marathon, showcases one of the most picturesque routes in American road racing. Beginning and ending in Franklin Park, the city’s largest green space, the 13.1-mile course takes runners on a serene yet challenging tour through Boston’s Emerald Necklace—a connected series of parks, ponds, and parkways designed by famed landscape architect Frederick Law Olmsted.
Start and Opening Miles
The race begins on Pierpont Road within Franklin Park, just outside White Stadium, where thousands of runners gather under the golden hues of early November. The opening miles carry participants along Jewish War Veterans Drive, Morton Street, and Arborway, leaving Franklin Park for the leafy expanse of the Arnold Arboretum.
These early sections roll gently uphill and down, offering wide turns and plenty of space to settle into rhythm. Runners experience a mix of shade and open sky, surrounded by vibrant fall foliage and the scent of Boston’s famous autumn air.
Through the Emerald Necklace
From the Arboretum, the course flows seamlessly into Jamaica Pond and Olmsted Park, where the route flattens out alongside the glistening water. These middle miles are among the most scenic of the race, tracing tree-lined pathways, ponds, and historic bridges.
At roughly the 6.5-mile mark, runners reach the turnaround near Willow Pond, a natural midpoint where the course doubles back toward Franklin Park. This section rewards those who pace wisely in the opening half; the gentle climbs on the return become more noticeable as fatigue sets in.
The Return and Final Push
The closing miles retrace the outbound route, giving runners a second chance to appreciate the parkway views while preparing for a strong finish. Small rises on Arborway and Morton Street test the legs before re-entering Franklin Park, where the crowds begin to thicken.
The final kilometer inside the park provides a thrilling finish: a gradual descent leading toward White Stadium, where spectators line the fences to cheer runners through the last stretch. The roar of the crowd and the sight of the stadium arch serve as the perfect backdrop for one final sprint.
Course Character and Strategy
