I have watched many great sporting performances over the years.....Klammer's down hill gold medal, Federer's various triumphs......Bolt setting unimaginable standards in the sprints. Even disgraced Bladerunner Pistorius in full stride at the London Olympics.
But nothing I have seen comes close to Alex Honnald free climbing El Capitan's 3000 vertical feet, captured in the documentary Free Solo. To me it's the supreme physical accomplishment in our sporting history.
If you have missed it...make the effort. It was nerve wracking watching it in the movie.....impossible to watch live for several of the camera men.
