I'm not trying to push running on you or anyone, nor am I saying that, "...running is required to be successful on the AT."
I'm just saying that it's a myth that running for years will inevitably lead to injuries that will require one to stop running. This myth is so common and it's just one of my pet peeves to counter myths.
That's not to say that some people have injured themselves for life from running, but whatever the reason it was not as simple as pounding; anyone that has run for any amount of time knows that the jarring you feel in the beginning is mostly from a weak frame and poor running form. Once one attains a higher level of physical conditioning and more experience you actually don't feel the pounding and actually feel more like you're gliding. That's not to say there is NO impact, but the body has very much the ability to withstand this impact, we've evolved that way and it's best to not shy away from impact, rather to confront it and condition yourself for it, that is the nature of nature.
Like I said, I don't care if you never run again, but if you do have some medical condition where impact is a major concern, than (as I said before) you really need to look at the why and make sure you do something to prepare for the AT, because hiking the AT ain't low impact. You can remove stress from your knees by using poles, but that will only add that stress to another location. You ain't getting any younger...
