Last week we were lucky enough to film an interview with Polar legend Pen Hadow. Pen shot to international fame in 2003 when, after fifteen years of unrelenting effort, he finally achieved his goal to become the first person to trek solo, without outside assistance, from Canada to the North Geographic Pole – a feat thought comparable to making the first ascent of Everest, solo and without oxygen, and one which has not been repeated since. Within months, he went on to become the only Briton to have trekked, without assistance, to both the North and South Poles. Pen has just returned from completing the Catlin Arctic Survey, a three month pioneering scientific expedition to help determine the lifespan of the Arctic Ocean's sea ice cover. The expedition, which is backed by the Prince of Wales, will supply the raw data to scientific organisations to analyse including Nasa, the University of Cambridge and the US Navy.
