On the second pitch of the spider I went slightly off route. I didn't follow the diagonal cracking to the right but went straight up. I got pumped and needed to rest. I put a cam behind a small flake and a small nut in a crack. Both were poor, but I had to rest. They held initially and then popped out. I fell and two further nuts, one on each rope and at the same height, also popped. A totem cam then held me. I fell about 15 metres, catching a small ledge on the way down but with no injury.
