“There’s an immense amount of sweat equity that he had to invest into this,” says Tejas. “Certainly, the opportunity with the time and money was necessary, but he went above and beyond what most people who are in the same situation do and decided to make a very disciplined decision to work really hard to accomplish his goals.”

In other words, you don’t get to Everest by sleeping in on the weekends before heading off to hang with your friends at the beach.

With each climb, Strange’s understanding of what could happen has deepened. On Mount Aconcagua in Argentina, he was caught in the middle of a rock slide and the extreme altitude crushed his video camera. On Alaska’s Mount McKinley, his sled slid into a crevasse, nearly taking him with it. And up high on Mount Everest, he had to pass by the frozen bodies of those who didn’t make it before him. “The one thing it taught was humility,” says Strange.

Even the easiest of the climbs -- or what was supposed to be the easiest -- offered its share of challenges. When the Stranges got to Australia’s Kosciuszko, the weather was no walk in the park. “You never should underestimate a mountain,” he says. “Everyone was saying, ‘Oh, it’s so easy.’ It [wasn’t] like there was any climbing difficulty, but you just couldn’t see. We had to literally use a GPS to find the top.”
