In September 2011, “Iceman” Wim Hof ran a full marathon in the Namib desert without water. The run was performed under the supervision of Dr. Thijs Eijsvogels. The Dutch daredevil who holds 18 world records for withstanding extreme cold, completed 26 miles in temperatures up to 40 Celsius atop Namibia’s Sossusvle. He didn’t touch a drop as he lost 5.2 litres of water and almost 14 pounds in weight, during the scorching run.

Using his uncanny control of his core body temperature, Wim applied the same logic of keeping warm in ice to staying cool under the burning sun.
Under the watchful eye of Thijs Eijsvogels, from Holland’s St Radboud University, he regulated his cardio-vascular system while being wired up to monitors measuring his blood pressure, heart rate and core temperature.
The 52-year-old adventurer said: ‘The run itself was very difficult and after around 10 miles my footwear had caused me bloody blisters which slowed down the pace dramatically.
“I carried on and suffered more because I didn’t drink any water during the marathon.
“This resulted in dehydration of my extremities. You could see that my hands thickened and that my feet ballooned too.’
