Together with his father and Wim Hof, Klaas Kroezen climbed to the summit of Kilimanjaro in just 48 hours in 2014. On making the impossible possible after all.
Together with my father and Wim Hof "the Iceman", I climbed to the summit of Kilimanjaro (5,985 metres) in just 48 hours in 2014. This normally takes 5 to 7 days.
Making the impossible possible after all. That is the power of a clear dot on the horizon. It has to be inspiring and challenging. I love it!
