Going for the full ~2,170 miles in one shot? How long are you expecting it to take? I'm hoping that at some point in my life I can try to complete it by doing sections annually.
Full. Doing a flip-flop. Start at Harper’s Ferry, WV and go north to Mt Katahdin in Maine. Then fly back down to Harper’s Ferry and go South to Springer Mountain in Georgia. Expect it to take me 6 months , give or take a couple weeks.
