Q&A: Alex Honnold, Simply "Psyched".

Alex Honnold competes in a sport more commonly covered by National Geographic than ESPN. Yet he's likely garnered more media attention than any other climber before him, for an obvious reason: He climbs giant, sheer walls (such as Half Dome and El Capitan) without using ropes or protection. It's called "free-solo," and it's the most dangerous kind of climbing.
