I guess you are young and foolish if you are thinking of doing the entire trail in 100 days.It’s been done in much less than that but only with support and the hiker carrying very little. #1) You will have to AVERAGE 22 miles a day and that is WITHOUT resupply in towns along the way. #2) Trying to time something like that perfectly is almost unheard of. I, personally, feel it would take a lot of the joy out of the trip by having to resort to a ridgid schedule of miles, etc. #3) If you want to continue to plan for this you may want to begin with a set of maps/trail guides which run over $200 new. You may be lucky to find a used set somewhere. #4) Gear. Get ready to lay out some sheckles for sleeping bag(s), stove, cook set, water filter, boots (2 pair), clothes, sleeping pad, tent, backpack, etc…Oh, save the backpack for last. No need to do overkill. Find out what you are carrying and then find a pack to fit it. Good luck in your endeavor and say “HI” if you see a grasshopper on the trail. :happy
