In 1996, polar adventurers Jock Wishart and David Hempleman-Adams organised The Ultimate Challenge,[1] in which they chose 10 Arctic novices from over 500 applicants and successfully led them to the Magnetic North Pole.
The overall results were: Teams included Special Forces soldiers, Richard Dunwoody (professional jockey), Steven East, Mike Krimholz, Jock Wishart.
Extreme cold temperatures were recorded at minus 47 [clarification needed] and a 4-day whiteout situation.
All six teams successfully reached the pole, but with one competitor retiring early due to minor frostbite (which later healed fully).
