Alexander J. Honnold (born August 17, 1985) is an American rock climber best known for his free solo ascents of big walls. He has broken a number of speed records, most notably the only known solo climb (mostly free climbing with a few points of aid) of the Yosemite Triple crown, an 18 hour 50 minute link up of Mount Watkins, The Nose, and the Regular Northwest Face of Half Dome. He and Hans Florine are the current record holders for the Nose with a climb time of 2:23:51. Honnold says that he likes tall, long routes and that he tries to do them quickly.
