Demonstration 'Iceman' Wim Hof, March 24, 2007, Rotterdam. About Wim Hof........... 'The Iceman'

One of Wim's world record attempts took him to the North Pole, where he held his breath for about 6 minutes and 20 seconds below the ice. Image courtesy of Innerfire website

(MountEverest.net) In January this year, Wim Hof ran a half Marathon (21 km) above the polar circle in Finland. He wore only a pair of shorts and no shoes. The ground (snow) temperature was 35 below. In a few months time, he'll try something similar on Everest's north side. The expedition, led by Dutch Werner de Jong, will try to set a new world record as Wim attempts to climb parts of Everest wearing only shorts.

This is not your regular stunt. Wim already has 9 world records, and has trained hard for many years to withstand cold, much like some monks do in Tibet.

Wim can actually regulate his core heat to control the temperature of his skin. Something of a medical enigma, Wim is able to withstand cold that could kill or seriously injure other people.
