I concur with Tommy Caldwell, Kevin Jorgensen and Alex Honnold. Incredible feat to achieve what they have. Wouldn't fancy sleeping in one of those portaledges! The Dawn Wall, Free Solo and Valley Uprising are all great documentaries too.
I used to do a bit of climbing with ropes on rock faces, mostly around North Wales and the Peak District. If I was free soloing like Alex Honnold I'd have died dozens of times by now! It's pretty telling that Alex Honnold is pretty much the only one doing what he does, most of the other ones have sadly died doing it.
