Fork Ridge to Road Prong is 2.4 miles.
Road Prong to New Found Gap is 1.7 miles.
New Found Gap to Ice Water Springs Shelter is 3.0 miles.
New Found Gap to Pecks Corner Shelter is 10.8 miles.
New Found Gap to Tricorner Knob Shelter is 15.6 miles.
Once you make the 1,000' climb from New Found Gap Road toward Icewater Spring Shelter, the elevation profile doesn't look bad. But I hiked from New Found Gap to Pecks last summer when I thought I was in decent shape. But for some reason, the trail between Charlie's Bunion and Pecks seems to take an awful long time with at least 1,500' in accumulated elevation gain.
Pecks to Tricorner isn't any better with at least 1,000' in accumulated elevation gain.
So Road Prong to Tricorner likely has more than a 3,500' accumulated elevation gain over 18 miles.
(That looks to be about on par with trying to go from Fontana to Spence)
