Injured servicemen and women from the U.K., the U.S., Australia and Canada arrived in Iceland in early March to train for the Walking with the Wounded race across Antarctica.
The teams took part training exercises on Langjökull glacier, West Iceland, camping out on the glacier and melting snow for water each morning during their two weeks in Iceland, dailymail.co.uk reports.
Among the group are Ivan Castro, who is blind, and Sergeant Duncan Slater, who is hoping to become the first double-amputee to walk to the South Pole.
Other members of the group suffer from post traumatic stress disorder (PTSD) and gunshot wounds.
The aim of the race, which is scheduled for November, is to raise the profile of injured service men and women and to encourage donations.
