Climbing the Wall

Being stuck on the side of El Capitan can be both freeing and confining — not unlike a lazy day on the couch, minus the cold, the occasionally brutal winds, the periodic chunks of ice that fall like meteors and the stress of preparing to continue one of the great climbing expeditions.

That is why they do so-called ledge yoga, performing poses to stay limber. For as much exhilaration as the men get from climbing, and as much downtime they have between surges, there is one thing they desperately miss from the horizontal world that many might not imagine: a place to take a few steps and merely walk.
