In reply to gaffer:
Sharma's route on Clark equates to a F9b or 5.15b. It's almost 100 meters long with 30 meters of 14c climbing up to a 15b crux, then 20 more meters of 13d. I think most climbers in N. America consider it to be the hardest route in the world but there hasn't been a second ascent yet so we don't know for sure. It's a sport route. There are 6 or 7 in the world now and only one has seen a second ascent. Adam Ondra did one of Sharma's 9b's in Spain.
Sharma also did Realization in 2001 which was the worlds first 5.15a/9a+. Es Pontas was his DWS route in Spain that is said to be 9b but no one has repeated that either. Who knows... but Requiem is a traditional route and Sharma's are not. Neither are any of Danny Andrada's routes, who I believe is the only other climber to do a first ascent of F9b.
Beth Rodden did Meltdown a few years ago on natural gear and it was said to be .14c or 8c+. I don't know the UK system that well but was under the impression that .14c is 7b E12. I do remember it being regarded as the hardest trad route in the country... maybe the world. I've also seen the same thing written about Requiem at E11.
It's rather silly to compare Sharma to McLeod though. Sharma wouldn't try Requiem and Mecleod couldn't red-point Jumbo Love.
I personally think Sharma's routes get a lot more press, but will probably be repeated before McLeod's routes are repeated. Wonder why Honnold and crew didn't try Requiem. Or did they?
