Adventurer Pete Goss is leaving the UK for Greenland, where he will walk across an ice cap in preparation for a trek to the South Pole.
The Greenland trip will prepare him for his South Pole trek
Mr Goss and polar explorer Alan Chambers, 34, from Taunton, Somerset, are to spend 17 days training in Greenland ahead of their expedition in November.
The pair want to become the first team to walk to the South Pole and back using the same route as Captain Robert Falcon Scott.
Forty-one-year-old Mr Goss is best known for his bid to sail the Devon-built £4m carbon-fibre catamaran Team Philips in The Race, a no-rules round-the-world sailing event in December 2000.
However, the 120 foot (36.5 metre) long vessel had to be abandoned after it began to break up at sea.
While in Greenland, they will test two giant kites which they plan to use during their trek to help move their sledges.
Mr Goss, who is based in Cornwall, said: "This is a dry run for the Antarctic.
"We have to be at the top of our learning curve when we get there. We need to hit the ice running."
The South Pole expedition is to raise more than £300,000 for HopeHIV, a charity which helps children orphaned by Aids in Africa.
