I watched some of it on Channel 4 last night.
I was slightly disappointed, as the programme was a bit slow and ponderous, even though the subject matter interested me.
The programme could have been shorter, and more to the point of just how great an achievement it was to climb one of the worlds most challenging rock faces solo and unaided.
I did not realise El Capitan was so high, just 350ft lower than the height of Snowdon, that's a seriously high rock face.
I much prefer the documentaries about Alain Robert, the French free climber, who has coined the phrase URBAN FREE SOLO scaling most of the worlds tallest buildings, mostly without permission.
His film documentaries are so dramatic, that its compelling tv, when last nights Channel 4 programme was not as interesting as it could have been.
Just check out his You Tube Video titled "Inside Tour Total" Totally nuts !!!!!!!!
