Watch Alex Honnold Climb a Skyscraper

The athlete's urban journey will be aired live on national television

Rock climber Alex Honnold, 27, will take on a new challenge this fall when he climbs one of the tallest buildings in the world. The adventure, called “Live Climb with Alex Honnold,” will be aired in real time on the National Geographic Channel.

"I've always loved climbing in all forms and this is an amazing opportunity to push my own climbing into interesting new terrain,” Honnold said in a statement. “I've admired the aesthetics of sky scrapers my whole life; it's great to be able to climb one.”

Normally, scaling one of these massive buildings would be illegal, Honnold pointed out in an interview. In this way, the deal between Honnold and National Geographic was beneficial for both parties.

"When Alex brought us this incredible idea, it struck at the very heart of what a National Geographic global television event should be," National Geographic Channel President Howard T. Owens said in a statement. "Alex is the world's premiere free-climber, and we are excited to celebrate his adventurous spirit as he tackles his next challenge."

While the attempt may sound crazy, it’s not so far off from the other seemingly impossible feats Honnold has accomplished in the last decade. Honnold is considered an expert in free climbing—that is, scaling massive rock faces without any safety equipment. While Honnold’s climb up Yosemite’s Half Dome may have skyrocketed him to stardom, he has completed numerous other (and more dangerous) climbs since. These include an approximately 18-hour ascent of the Yosemite Triple Crown (Half Dome, El Capitan and Watkins) and a triple crown in Zion National Park—the feat Honnold called the hardest of his career.

For safety reasons, the exact location of the climb will not be released until closer to the event. Stay tuned for more information.
