I clicked on their pics, and they are some of hiking in 2000. Judging by the captions to the photos, there are at least 2 of them that did SOME hiking time on the AT. However, they encountered some issues, I think healthwise, that caused them to cut a 2 week trip short.
Now, 2 weeks on the AT, IMHO, does NOT equate to outdoors skills. The AT is often referred to as a "moving city". And, MANY, MANY people hike the whole thing, with NO previous experience in the woods at all. The nice part of the AT is that, practically any time of the year, SOMEONE is bound to run across you within a day if SHTF. So, there is a safety net there.
I gave them some things to think about on their blog; however, I am leaning towards them failing. I DO have it marked to watch though. I'd be surprised if they even start on this.
And, every time I go camping now, I am doing it for a noble reason! They have INSPIRED me!!
Ok, just kidding. I do it to get away from people
