Sir Ranulph Fiennes
Ran was the first man to reach both poles by surface travel, and the first to cross Antarctica unsupported. He’s also the oldest Briton to climb Everest, has run seven marathons on seven continents in seven days, as well an ultramarathon in the Sahara. He undertook the first expedition to attempt to cross the Antarctic continent on foot during the southern winter, at temperatures of minus 90C; but sadly frostbite forced his withdrawal. Despite the setback, Ran believes that “If you are lucky enough to be able to walk without a crutch, you might as well go for it.”
