If you've ever pushed yourself doing anything physical, you'll enjoy this. The feeling of giving more than you have to give, and really pushing it until you feel you will.... explode. Mine was running, and reaching that plateau on a plane where nobody else was. Your pushing so hard, and everything is in sync. You have done it for years and only the unforseen "oddity" failures can remove you from competition. You're good.
Then, when you see people that race up the side of a mountain where 1 in 3 die, and they are doing this without ropes ....well...you realize you haven't done much of anything. Through the doc they are very well spoken, normal, grounded even. But this goes beyond any of that. You look for some reason for there to be a death wish...and it's not there.
These are just people racing up some of the most hellified climbs on the planet......for the hell of it.
More than once watching this I found myself at the edge of my couch, in full cringe mode as they depend on a hook, grab or step to breathe again.
Wow man.
