In reply to riff156:
Many years ago (10 I think). I was in El Chorro and we planned to do Africa.
We made our way into the gorge on the old broken Camino del ray (a fun experience in itself) and through the little tunnel to the ab point for Africa.
Now the issue we had was the guide specified a certain length of ab rope, 70m I think, and we only had a 60m rope.
My climbing partner told me over and over again the rope wasn't long enough, however I was adamant that we would be able to sort it, there would be an intermediate belay etc.
So I set up the ab and off I popped Into the unknown. On the way down I spotted a ledge below me off to the left and convinced myself i would be able to reach it on the rope, so I carried on.
I reached the end of the rope and realised I was nowhere near the ledge I had seen, furthermore I was now just hanging in space as the rock in front of me was overhanging and had pushed me out and away from it.
Luckily I had tied a knot in the end of my ab rope, however I was now just dangling in space a good hundred or so feet above the gorge floor and the only thought running through my head was 'I WISH I HAD PURCHASED CLIMBING TRAVEL INSURANCE'.
My climbing partner, sat in safety about 100 feet above me thought my current situation was rather amusing, I did not agree with him.
Just by chance, not prior planning, I had a sling attached to my harness which I was able to use as a prussik. After lots of huffing, puffing and pulling I was able to make sufficient upward movement to put myself in a position where I was able to vigorously rock backwards and forwards until I gained enough momentum to make contact with the rock infront of me.
Once I latched myself to the rock, which on this part of the crag had the consistency of a digestive biscuit, I hurriedly tied myself into the rope using some kind of gigantic granny note, yelled to my partner to take in and I climbed/swam back up to the ab ledge.
As I pulled myself onto the ledge and collapsed, an exhausted, sweaty and dirty mess my climbing partner looked down at me and calmly said 'I told you the rope wasn't long enough'.
