In reply to jon: Back in 1989 when the Spanish were just getting started, Carlos Garcia soloed both Zulu Demente and the more sustained Fiesta de Biceps:
‘I look down into space, I hang from an arm, without distance, alone, free, it is worth absolutely nothing, there is no hope. The past does not return and no move is repeated. If you fall, no-one will pull you in and let you down softly to the ground, you burst open’. One of the most inspiring deeds of the '80s. (Obviously he carried on up).
Maybe some Guildford 6b punters can take up the challenge. I suspect by the time they get to the last pitch they will be quite impressed. They have three choices: go up, go down, or write a letter to the guide book editor complaining about the 6b obligatory grade. As an encouragement the bolts are close on the crux. But you still need power to connect them. For the experienced, retreat is possible but laborious and not a place to learn. Better to have the power.
As a 6a+ punter I have resisted the suggestion to do this route, though I would dearly love to do both ZD and Carnavalada. As Chris Bonnington said in his well written recent Summit article up to 50 you can bounce up routes, after 60 you just creak. Marvellous outings for the able, as Leo and Carlos Suarez demonstrate.
