I’ve done the LT NOBO on july. I’ve found that times from shelter to shelter in the E2E guide are always longer than what it really took me. In general I did in 75% of what the guide says. But it’s sure that it depends on each person. But these times were useful in that I was always at 75% of what it was supposed to be.
There is one section which is really longer than that the guide says. It’s to reach Montclair Glen Shelter by the south. Every person that I know from the trail will say you the same thing.
Number of days to complete a thru hike is a good question. At first I planned to do it in 20-21 days. Physically I was more than able to do it. But after few days I’ve just realised that to take shorter days would means more fun. I’ve realised what makes real pleasure on the trail: swimming, food and most important, people. If you go too fast you will be always alone and loose everybody behind you and maybe pass beside opportunities of making good friends.
I did the whole trail in 26 days and it was, physically, easy. I’ve met two hiker who did it in 12 days. I don’t have to say that they didn’t see anything interesting alog the trail!!
If you have enough time I would just recommend you to don’t plan too mush. Walk when you want to walk and take breaks when you want to take breaks. The most important thing, after all, is to enjoy you hike every day.
And finally, if you can, plan some days after the end to just relax. You will see how the trail change you deeply and you will need time to return to “real life”. Be aware it can be a big shock!!!
Enjoy you experience
