Watch this... some nut job free solo speed climbing a 400' wall. Its amazing to see that the human body can be trained to do something like this. The part I can't believe is he does a dyno about 3/4 of the way up. For those of you who don't know a dyno is a dynamic movement. He basically jumps from one hold to the next. The chances of missing that is pretty high, and when the concequences are this big.... fuck... just crazy. Makes a 100' jump seem like pussy shit.
