Alastair Wilson, the great-great nephew of Edward Wilson, is training for an expedition north of the Arctic Circle.

Artist Edward Wilson was one of the crew who perished on the ill-fated expedition to the South Pole in 1912.

Alastair, 24, from Tegryn, Pembrokeshire, is joining a sponsored dog sledge in Norway to raise money for the Scott Polar Research Institute.

Alastair, who works for the Countryside Council for Wales in Bangor, said it would be a big challenge as he had never been further afield than Ireland before.

"With my great-great uncle having gone down to the Antarctic with Captain Scott there was a strong family tie," he said.

Obviously it's going to be a lot of hard work, it's going to be cold and we'll have to get used to working with the dogs Alastair Wilson

"The SPRI is a charity that does lots of research into climate change, polar biology and also runs a museum dedicated to Captain Scott and his expeditions."

Scott and his team reached the South Pole on 24 January 1912, but hit bad weather on the return trip.

Edward Wilson died alongside Scott and two other crew members in a tent on 29 March.

Alastair will join a group of other volunteers, aiming to raise over �3,000 each, for the expedition in March.

They aim to cover 250km in five days, sleeping in small shelters and tents.

He will be responsible for his own dog team, learning to harness them and drive them during the day and tethering them at night.

"Obviously it's going to be a lot of hard work, it's going to be cold and we'll have to get used to working with the dogs," he added.

"I am training - I'm doing a lot of walking to build up my stamina.
