For those who are planning an upcoming AT thru-hike, I've attached a link to my 2013 AT thru-hike (GA-ME). I started 3/21/13 & finished 8/19/13 (152 days). As I hiked, I kept track of my starting times & ending times each day. At the end of the spreadsheet, I included the average, mean, earliest, & latest times that I started & ended.
On the trail, I primarily stayed in shelters for convenience. I tended to start hiking earlier than most (usually the first to leave). As a result, I never reached an intended shelter that was already full.
For reference, I was 58 yrs old when I started the hike. I finished the hike a few days short of my 59th birthday. I have been a regular runner since 1978 (although I have slowed considerably over the years). I am a very experienced backpacker. I'm a steady hiker (slower than most) but usually don't take too many breaks. I kept a modest pace until Damascas. Afterward, I would often shave a day off between resupply locales. I did slow down from my intended pace in the Whites & Maine.
Anyway, I hope this information is helpful.
