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.
