Walking with the Wounded South Pole Allied Challenge

ANTARTICA - DECEMBER 13: In this handout image provided by Walking with the Wounded, Prince Harry (L) and Ivan Castro touch the pole as they and their fellow adventurers reach the South Pole as part of their Walking With The Wounded charity trek on December 13, 2013 in Antartica. The Virgin Money South Pole Allied Challenge 2013, of which Prince Harry is patron, will see the participants race across three degrees to the South Pole. All 12 injured service personnel from Britain, America, Canada and Australia have overcome life-changing injuries and undertaken challenging training programmes to prepare themselves for the conditions they will face in Antarctica. Trekking around 15km to 20km per day, the teams endured temperatures as low as minus 45C and 50mph winds as they pulled their 70kg sleds to the south pole.
