Running in Boston

Running parallel to the Emerald Necklace but connecting a different set of neighborhoods, the Southwest Corridor Park is a linear park and paved path that stretches roughly four miles from Back Bay Station through the South End and Roxbury to Forest Hills. The park was built in the 1980s on top of the relocated Orange Line subway tunnel after a planned interstate highway extension through the neighborhood was cancelled, and it now functions as one of the city's longest uninterrupted green running corridors. Runners use it to link the South End's brownstone blocks to Jamaica Plain without crossing many major arterial roads, since most street crossings are handled by bridges or signaled intersections built into the original design. Unlike the Esplanade, the Corridor rarely gets crowded because it runs through residential rather than tourist heavy areas, which makes it a favorite for tempo runs among Boston residents who already know the Charles River path gets busy.

At its southern end near Forest Hills, the Southwest Corridor connects into the Arnold Arboretum section of the Emerald Necklace, so a determined runner can string together the Corridor and the Necklace for a long run that touches Back Bay, the South End, Jamaica Plain, and Franklin Park without much repeated ground. The path includes basketball courts, community gardens, and playgrounds along its length, giving it a neighborhood feel that differs from the more manicured landscaping of the Emerald Necklace parks to its north. Because it sits at street level rather than along the waterfront, the Corridor also offers more tree cover in summer, which some runners prefer over the open, wind exposed Esplanade. Local training groups sometimes use the Corridor's flat, straight sections near Ruggles for controlled interval work since mile markers are easy to estimate using the cross streets.

For Boston runners who want real hills rather than the rolling bumps of Newton, the Middlesex Fells Reservation just north of the city in Medford, Stoneham, Winchester, and Malden is the default answer. The reservation covers roughly 2,500 acres of forest and rocky terrain, and its Skyline Trail is a rugged loop of about seven miles with repeated steep climbs that make the Charles River Esplanade feel flat by comparison. Because the Fells is accessible by the MBTA Orange Line to Oak Grove Station, runners without a car can still reach genuine trail terrain in under thirty minutes from downtown Boston. The reservation's network includes more than a hundred marked trails beyond the Skyline Trail, so it also works for easy recovery runs on softer footing away from the steeper sections.

Trail conditions in the Fells vary more than anything runners encounter along the river, with exposed rock, roots, and after rain, standing water on some of the lower loop trails. Many marathon training groups in the Boston area schedule one Fells session every few weeks specifically to build the kind of leg strength that pays off on the Newton hills late in a spring marathon. The reservation also has several reservoirs, including Spot Pond, that provide flatter out and back options if a runner wants to mix easier miles into the same outing as a harder climbing segment. Because the Fells is far less crowded than the Esplanade or Emerald Necklace, it has become something of an insider spot, recommended more through word of mouth at local running stores than through typical Boston running guides.
