Myself and a fellow hiker have been wondering...what exactly is the 4 state challenge? I'm currently thru-hiking and in Troutville VA. One person told me it is from the last shelter in VA to the first in PA in 2 days (aprox 67 miles). Another said it is from The VA/WV border to the MD/PA border in 2 days (aprox 58 miles). Another said it was the same 58 miles in one day. Frankly I am going to try to hike Maryland in a day after I zero at home near Annapolis, but I would like to know EXACTLY what the challenge is (if their is such an exact thing), since a large number of us current thru-hikers do not know. Thank You, Beatbox.
