Another time I read LOTR in order to enjoy the account of the journey itself. I loved the detail with which the walking was described, the countryside, the weather, and the effort of moving through it carrying a pack. Tolkien walked a lot and must have done a fair bit of backpacking too. It adds so much to the credibility of the characters and their journey. Real-life backpacking does get sweaty, there are sometimes uncomfortable numbers of midges, trails do get confusing.
Time is spent every day setting up camp and taking it down again.
At that point I surfaced from the book thinking, 'Oh yeah, heroic fantasy, I forgot. Nobody needs to eat. I don't think so. A summer backpack holding one jersey, something to sleep on, something to sleep in, five days' food and something to cook it on makes a load about the size of my own body. Unless we're talking that freeze-dried stuff from tramping shops which I don't think Simon Snowlock was using either.
