Wim Hof is a Dutch world record holder, adventurer and daredevil, commonly nicknamed “The Iceman” for his ability to withstand extreme cold. He is the creator of the Wim Hof Method and holds more than 20 world records. Wim is an outlier of outliers, and he routinely asks scientists to scrutinize and validate his feats.
Hof holds the current Guinness World Record for the longest ice bath, now set at 1 hour 53 minutes and 12 seconds. He has climbed past the “death zone” altitude on Mount Everest (~7,500 meters) and completed a full marathon above the polar circle in Finland in temperatures close to −20 °C (−4 °F) dressed in nothing but shorts.
Hof can run at altitude without suffering from altitude sickness and has proven under doctor supervision to be able to effectively control his autonomic immune responses using only his meditation and prep techniques.
