Greenland is, by area, the world's largest island, yet with a population of under 60,000, it is the least densely populated dependency or country in the world. In May 2012, Ben Saunders, Martin Hartley and Alastair Humphreys spent 14 days in Greenland on a training expedition. This was preparation for their expedition in Antarctica next year.
In October 2013 Ben and his team mates will attempt to make the first return journey to the South Pole on foot. At 1,800 miles it will be the longest unsupported polar journey in history. For more information visit bensaunders.com
