Team members training in the Cairngorms

Exercise Nansen's Endeavour will see them attempt to retrace Norwegian explorer Fridtjof Nansen's route across the ice cap in 1888.

Team members, who have already trained in the Cairngorms, are to head to Norway next week.

Their expedition is expected to take about 35 days, starting in August.

Wearing skis, they will pull 80kg sleds 450 miles from the east to west coast.
