 Although not unsupported, there were strict rules on the carrying of equipment, with only food, fuel and camera batteries permitted to be replenished at the three checkpoints along the route.This event should not be confused with the Polar Challenge, which was a different event taking a different route, and run by a different organisation.In 1996, polar adventurers Jock Wishart and David Hempleman-Adams organised The Ultimate Challenge, in which they chose 10 Arctic novices from over 500 applicants and successfully led them to the Magnetic North Pole.
