Walking a long way

I’m not sure what it is, but the idea of walking a really long way appeals to me is some kind of primal way. Cradle Mountain, the Appalachian trail, perhaps something in New Zealand. Cycling a long way, too, has its appeal. I’m not quite sure why this is. Perhaps some sort of naive yearning for a return to a mythical golden age of nomads, when the human species was more in balance with its environment.

Recently though, a friend proposed the ultimate slog. Travelling from Northern Scotland to the southern most tip of South America, entirely by human-powered means. Swimming, walking, cycling, kayaking would all be in. Motorised transport – out.

Am I crazy to be considering this?
