i just re-read your post on ets and realised you said you had never hiked before.
DON'T try and do the pennine way, you simply have no chance of achieving it. i did it when i was 21 a cross country runner and a constant walker who grew up on the pennines and it was still very tough. i was lucky to have two companions who were fit enough to do it, we were the only group we met who finished with the party intact. i think it's 9 out of ten people who start off dont' finish it. you don't mention whether you have companions; you'll be lucky to meet anyone this time of year doing it and hardly anyone manages it alone.
especially don't do it now it'll be wet cold and dark and since the path is badly signposted very difficult to follow. the trodden down grass from previous walkers was such a help in finding the way. we did it in 16 days with one day off. walking 12 hours a day; you won't even have 12 hours of daylight. that 15 miles a day is constant up and down, it's not as easy as it sounds.
i'm alarmed you appear to have no equipment; you mean you don't have a broken in pair of boots and don't know how to use a map and compass? that is crazy!!
the survival advice on this site is not suitable for where you are going. there's nothing to burn on the moors and no wood to make bivouacs etc. i've been hiking here all my life and don't know how to make a fire. i've never been anywhere i could.
you are never more than 3 miles from a road in england so your survival equipment should consist of a moblie phone whistle and a bivvy bag. i'd bring a sleeping bag too this time of year.
but again the best advice is not to go; the pennine way is far out of your reach; try for something pleasanter. stick to florida.
