In reply to Martin Haworth:
Pretty sure anybody can enter. I had some friends do it last year that weren't elite. Afterwards there's a big dinner / piss up. If you're thinking of trying to place high up, you obviously need to be pretty effin good.
Looking at the website there's currently only 4 teams signed up (participantes tab). You can sign up via the incripciones tab.
There are some basic rules too, mainly: no simul climbing, no simul rappelling, you have to wear a helmet and you have to use two ropes.
