A father of three is training to take part in a rugby match at the North Pole, including how to deal with the threat posed by polar bears.
James Harding, 40, from Piltdown, East Sussex, will trek to the magnetic North Pole in an attempt to set a Guinness World Record by playing the most northerly rugby match in history.
He is part of group of 15 people taking on the challenge.
It is hoped the adventurer will raise £300,000 for the charity Wooden Spoon.
"There are harrowing winds, it will generally be about -30C, but if those winds pick up it will get to -50C," the investment director said.
"It is polar bear territory, we've had some specific polar bear training on that basis."
The team is scheduled to head-off in April and expects to take six or seven days trekking the 100 miles over the ice.
