<p>As xrCalico23 says, there’s not much in the way of hills in Cambridge, though there are hills in various points in Boston and beyond – Beacon Hill in downtown Boston, and Hearbreak Hill on the Boston Marathon route, for example. For running in Cambridge, you can create routes in and around Harvard, along the Charles River, and around Fresh Pond.</p>
<p>Blue Hills Reservation south of Boston provides a more serious hill experience – Great Blue Hill gets to a height of about 650 feet and there are a number of trails on the reservation’s 7,000 acres. Middlesex Fells is also a good place for hiking. </p>
<p>For more serious hikes, head for the mountains of New Hampshire. Mt. Washington, New England’s highest peak, tops out at a little over 6,000 feet. That might seem low in comparison to the Rockies or the Sierra, but timberline in that area is below 5,000 feet, so there’s extensive alpine terrain.</p>
