The White Mountains Hut Traverse is a gnarly 49-mile route that links 8 huts operated by the Applachian Mountain Club (AMC), between Carter Hut and Lonesome Lake Hut. Fast trips on the route go back at least to the 1930s (see below, and this site, and here).

The Monadnock-Sunapee Greenway Trail (MSGT) is a 48 mile long hiking trail that links Grand Monadnock with Mount Sunapee in southwestern New Hampshire. It winds along the Monadnock Highlands that divide the Connecticut and Merrimack River drainages. It is maintained by the Monadnock-Sunappe Greenway Trail Club.

This is a great Catskills loop I have done a number of times. It is possible to start in a few places and go different directions but I started at the end of Spruceton Road (rt.6) at the PA for the Spruceton trail up Hunter. I ran up the Devils Path and down the Spruceton trail with a .75 mile detour to the summit register of Leavitt mtn. (SW Hunter).

The West Rim trail is located in Lycoming County, PA, and runs along the Pine Creek Gorge, the grand canyon of Pennsylvania. en.wikipedia.org/wiki/West_Rim_Trail I wrote a little about it here runningforthefridge.blogspot.com/2013/05/completing-west-rim-trail-womens.html. I can't wait to go back and run it again.
