Honnold had practiced individual segments multiple times before this attempt. Those practice runs had left rubber marks on the walls, which helped him in following a specific route. Before attempting the complete climb, Honnold verified that the rubber marks were not removed by the rains. Plus, he has a daily regimen of specific exercises, so many freeclimbs before, etc. A complete professional, not an idiot for sure.

Here are more details about this climb and his preparation: http://www.nationalgeographic.com/adventure/features/athlete...

Chark marks explicitly put there to 'tick' hand and food holds -- to make it easier to see the holds and follow the sequence of moves needed. Not rubber marks from shoes.

He's an idiot because he has different values and priorities than you? I'd say that's pretty damn presumptuous. Who are you to tell him (or anyone else) how to live (and die)?

In the end it's his choice.

"at his incompetence" ? Your nickname is aptly chosen, yet the same can't be said of the words in your post.

Honnold climbs without a rope because he can afford to do so. He may well one day lose his life, but he knows it, and puts much more care in preparing and then stays concentrated on his climbs than most people do when driving a car.

I encourage you to read articles about him, they should help give you some perspective.

What is this? Of course he stays more concentrated than most people when driving a car because one doesn't have to have that kind of concentration when driving a car. Most mistakes while driving a car are not fatal.
