Dani Andrada has onsighted the 400m 13 pitch Zaratustra, ~8a/+, on the Pilar del Cotatuero, Spain. The free version of the route was put up by Manu Cordoba and Mikel Zabalza in 1997, and first freed by the Pou brothers.
Although best known as a single pitch sport climber, the Spanish Machina is no stranger to multi-pitches, having done routes like the 6 pitch Lurgorri, ~8c+, and Hotel Supramonte, 8b, previously.
When I talked to the man a couple of years ago, he said he had found a possible multi-pitch project in the Verdon Gorge, with pitches that could be around 9a or 9a+. I haven't heard anything more about this since then, but as he's coming to Stockholm in 10 days or so, I'll have a chat with him and try to find out more.
