Finland’s Arctic Circle may not be the ideal spot you have in mind when running a marathon - unless your name is Wim Hof.
Better recognized as The Iceman, Hof is a Dutch motivational speaker and extreme athlete recognized for his capability of resisting exceptionally low temperatures.
Born on 20 April 1959, Hof first began experimenting with the extreme cold as a teen.
He would sit outside in the snow for hours and would often sleep outdoors during the winter without a tent or a sleeping bag.
