A couple years ago I remember being impressed with Edmund because he did the ultimate hike, the Pacific Crest Trail, which runs from Mexico to Canada. And he didn't just hike it, he speed hiked it, finishing the trail about two months faster than most people by wearing and carrying the barest essentials. I got to talk to him about it for a short while, but I've been meaning to do a lengthy interview with him as I find it a fascinating trek requiring superhuman stamina.
Now I see he's doing it again. Hiking the PCT takes about two years of preparation, and you have to be able to put your life on hold for about six months while you hike. A small number of folks try it each year and a very small number finish. I can't begin to describe how insane it is to do a 2,700 hike twice in just a few years.
