I'm planning a section hike this summer from Grafton Notch SoBo to Rte 2 near Gorham. My ride needs to schedule vacation time to drop me off and pick me up, so I'm trying to get an idea of how many days this will take. I usually carry about 25 lb pack, hike 12-15 mpd on moderate terrain, did 10-12 mpd in NH from Hanover to Lonesome Lake hut. Is it possible to do these 31 miles in 3 days, or since it includes Mahoosuc Notch and Arm, is 4 days more realistic?
