I just did some research on this a few weeks ago for another thread. I’ll repost the relevant parts here.
The only source I could come up with (Roland Mueser’s Long-Distance Hiking: Lessons from the Appalachian Trail) that mentions this with anything like currency states that Wardrow Leonard (“Spooky Boy” AT’90) is the fastest unsupported thru-hiker at 61 days. The problem is that the records on this just aren’t kept in any systematic way. You’d have to try and survey all the sign-in sheets from Amacalola and Khatadin to really get a handle on it and no one seems to have done that. Someone may have done it faster than Leonard, but it just hasn’t been noticed or reported.
For records, you have to turn to those who are obsessed with them, the ultra-trail runners. The record for them (supported, of course) now stands at 47 days, 13 hours and 31 minutes, set by Andrew Thompson in 2005.
In response to this post, freebird added some rather interesting personal info that I’ll quote:
I met Ward on the A.T. in '96 in Boiling Springs, PA. He was a legend at the time on the trail for a number of reasons, including his speed hiking ability.
We had a fund-raiser for a thru-hiker named Skylark at the Italian restaurant in Boiling Springs that year. (her pack had been stolen at the ‘Dog Patch’ tavern in MD) Anyways, Ward was invited along with the rest of us who were strung out on the trail both north and south of Boiling Springs. “The Honeymooner’s” shuttled hikers to and from the party in their truck. Ward was about 48 miles south of Boiling Springs about mid-day. He refused the free ride into town offered to him, and said that he would hike to the party. Sure enough, around 8 PM he crashed through the doors of the restaurant, sweating from head to toe and wished ‘Skylark’ a happy birthday (he assumed it was her birthday party) and then ran off into the night.
Two days later, he was arrested on the steps of the ATC regional office for terroristic threatening. He was unofficially banned from the AT, although he has been spotted a couple times since, using psudo-trail names. The trail name which he used for years was “Spooky boy” which was apropos - he really enjoyed scaring hikers, especially at night.
Besides his speed record, he is the only hiker to complete a double “yo-yo”. He hiked from Springer to Katahdin to Springer to Katahdin in one year.
So apparently to set an AT speed record, you have to be, shall we say, a little outside the norm even for a hiker (well, we’re all a little crazy.)
