British explorer Sir Ranulph Fiennes is to lead the first team on foot across Antarctica during the southern winter.
The six-month expedition next year is being called the Coldest Journey, crossing terrain where the temperature has hit -90C.
The BBC's Matthew Price has been following his preparations for some months.
He caught up with the team while they were testing their equipment in the town of Arjeplog, close to the Arctic Circle, in Sweden.
