Appalachian Trail, Killington, Vermont
Why Run It: One hundred and fifty of the most scenic miles of the Appalachian Trail run through the state of Vermont, and the section near Killington is the place to go in the fall. Just ask former Appalachian Trail record holder Jennifer Pharr Davis: "The Vermont stretch of the AT is one of my favorites because you can combine the AT and Long Trail, and hit the Long Trail Brewery when you're done." Start a run at Kent Pond in Gifford State Park, part of the Green Mountain National Forest. Hop on the AT and run out-and-back heading west. At the Willard Gap/Maine junction, the AT joins the 270-mile Long Trail. If you're up for it, continue on toward Killington Peak (4,241 feet) with its outmatched views, 9.7 miles from where you started.
