A Guernsey man has had to abandon a world record to ski to the South Pole because of a torn ligament.
Jason De Carteret, 41, was part of a two-man team taking part in the Sub-Zero Antarctic Expedition.
But the injury to his calf muscle has meant he has turned back leaving his team mate Todd Carmichael, 44, to continue the expedition alone.
Mr De Carteret is in daily contact with his friend who is continuing in his bid to break the record.
The pair left for the Antarctic at the end of November and planned to cover 745 miles (1,200km).
They faced temperatures of more than -70C and winds of up to 124mph (200km/h) as part of their challenge to ski from the coast to the South Pole .
Both men are seasoned trekkers in extreme conditions and were taking part in the challenge for a number of charities.
