As a climber, 28-year-old Alex Honnold shares the record for the fastest climb of El Capitan in Yosemite and he's the only person to solo climb Yosemite's Triple Crown in one marathon climb. More recently though, he climbed the the "ruins" at the Palace of Fine Arts, the Mark di Suvero sculptures in Crissy Field and the precarious brick facade of 720 California Street.

The video above, which will thankfully only induce a mild sense of vertigo, was produced by the public media folks at KQED and Stride Health, which is a health insurance startup based out of San Francisco.

Update: in an email sent to SFist at 5:53 PM Friday, KQED Forum Senior Editor Dan Zoll says "KQED was not involved in the production of the advertisement in any way, and the Forum audio was used without our permission. KQED sent a takedown notice to YouTube and a Cease and Desist letter/email to Stride Health today." SFist regrets the error.
