Ranulph Fiennes' Coldest Journey: the blog

Sir Ranulph Fiennes, he of monstrous, explorery man-parts, is about to embark on a 2000-mile journey across the Antarctic, making him the first man to cross it in Winter. And by cross we mean WALK. Oh, and he's taking two modified bulldozers as back-up. In minus 70 degree temperatures.

The convoy of two adapted CAT 6DN track-type tractors (or, erm, bulldozers) double up as mobile science labs studying the effects of global warming, and the extreme sort of load-luggers. They'll stow enough food for a year, 112,600 litres of fuel, spare parts, medical paraphernalia, extra ski equipment (Ranulph's mode of transport)... the only thing they're not taking is water, because they can just melt the ice. And there's a fair bit of that in Antarctica...

And guess what? We've got a series of blogs filed directly from the expedition, as it happens. Click on to join the team.
