I know it is a fantasy book, but I wonder if anyone really had to go on a journey like Sam and Frodo, would they survive? Because by the end they did not have any water they could drink, they were starved, if they had to go on any longer, they would not have made it. I think also it maybe was a shorter distance than you would think, the entire Middle Earth area was (I think) about the size of Western Europe, so it was not as large as you would think.
