So, what’s the trick? How do these mad lads move so fast? First, you must be born with the lungs of a horse. Seriously, Sherpas have a genetic edge—their bodies process oxygen more efficiently at high altitudes.
Second, you need to be insanely fit. We’re talking Olympic-level cardio, but with a heavy backpack in a blizzard. These folks train by running up actual mountains for fun. They don’t call it training; they call it “Tuesday.”
Third, you have to have a brain that doesn’t process fear correctly. When the wind is screaming at 100 mph and the temperature is -40, most people think “I should go home.” A speed climber thinks “I can make up time here if I skip a breath.”
