Pen Hadow

Rupert Nigel Pendrill Hadow, known as Pen Hadow (born 26 February 1962), is a British Arctic region explorer, advocate, adventurer and guide. He is the only person to have trekked solo, and without resupply by third parties, from Canada to the Geographic North Pole. He is also the first Briton to have trekked, without resupply by third parties, to both the North and South Geographic Poles from the respective continental coastlines of North America and Antarctica. Hadow also led the Catlin Arctic Survey (2007-2012) which investigated sea ice volume, ocean acidification and ocean circulation. Provided by Wikipedia
