The guy who makes Survivorman seem almost a bit wimpy

Former British Army captain Ed Stafford, 33, is well on the way to becoming the first man in history to walk from the source of the Amazon in the mountains of Peru to its mouth in Brazil. And he's not doing it in the hope of achieving notoriety, nor is he being paid handsomely for his efforts. No, he's doing it out of a sense of adventure - for the sheer derring-do.

He is 612 days in - and looking to finish next August. If he achieves his aim, it will be a stupendous achievement, right up there with Hillary's ascent of Everest and the conquerors of the poles.
