Well, I’m a thru-hiker, but Lone Wolf certainly makes a valid point. Everyone should hike their own hike. And there should be more to an adventure on the Appalachaian Trail other than cranking out the miles. Stop and smell the roses.
And there is room for both. As I thru-hiker, I did a lot of miles. I didn’t have much use for towns, so I didn’t linger there. But, on occassions, I did linger at senic places along the trail. Overview Mountain is comes to mind immediately, but there were others. If you make an effort to get an early start in the morning, then there is time during the day to get some miles done, and to linger and enjoy the senery where you want to in route. The other thing that keeps your average up is to hike every day, and not get caught in the town suck. I never hiked big miles, but I hiked consecutive days, and that resulted in an overall average that was much better than most.
But, back to the inital question. It asked about daily milage, I answered it. Anyone who goes on a backpacking trip should have some kind of a plan and idea of how long they intend to spend in the woods, or between resupply points.
Sleeping Bag? Average weather records are from lower elevations. The AT is high, so you need to deduct say 15 degrees from published records. So, average low temperature is probably 45 degrees. Could get colder than that. I suggest a summer weight bag, say 40 degree, or a fleece blanket. I think that you will sweat in a 20 degree bag.
Bear bag? Just hang a regular stuff sack, at least 10 feet off the ground, and at least 4 feet from a tree trunk. Most of the bad bears are in Georgia, and there are bear lines at nearly all of the shelters. Didn’t hear of bear problems in NC/TN. Most of the bad bears have been chased out of the Smokies.
4 liters sounds like a lot of water. The ranger at Amicolola Falls State Park can update you with the water sources when you get there, but I’d probably carry 2 liters and count on filling up at least once during the day and in the evening.
