By now, you’ve seen Kai Lenny and Lucas Chumbo’s exploits at the Nazaré Tow Surfing Challenge. They won, of course, and they won because they’re both able to treat the hugest waves in the world like a playground. They’re both able to stare at horrifyingly big waves without blinking. You might’ve seen their exploits in real-time, but watching them in slow motion adds a whole new level of appreciation for what they’re doing.
