double presi done June 21, 2014
Route: Crawford Path trailhead on Rt. 302 to Daniel Webster Trailhead at Dolly Copp Campground, and back.
Peaks: same as for the one-way FKT -- Pierce through Madison.
Stats: 39.4 miles, +17,309' gain (from AMC White Mountain Guide Online)
Mode: supported (food taken from Madison and Lakes of the Clouds Huts)
I would guess this has already been done faster, and have no doubt that any of the usual suspects (Welts, Wilcox, Nephew, Welford)could run it much, much faster, maybe sub 11, if they wanted to.
