Welcome to the wildest competition known to man — the speed record on the Nose route of El Capitan. For 50 years, the best climbers in the world have been one-upping each other on this massive granite monolith in Yosemite National Park, racing up 3,000 feet of vertical rock in under three hours, and risking life and limb to shave mere seconds off the record time. We follow Dean Potter and Sean Leary on their attempt to break this legendary record on the classic route that has been the scene of epic rivalries, brutal accidents, and remains to this day a hotly contested prize.
