I knew the route was long and pumpy before starting and that this was my weakness, but I wanted to push myself. At about the 30m mark I was at the end of my endurance and a little way above my last gear. I noticed as I was trying to shake-out that the ropes (doubles) had slipped behind my heel. This caused me to lose all composure and I began to peel off. I managed to shake one of the ropes free before falling and I don't recall the other rope snagging on my leg as I attempted to fall in such a way as to free it; however, in the process of trying to free the other rope I pivoted over backwards and inverted anyway. As I was falling I heard my latest gear (a 00 cam) pop but was caught on my next two bomber nuts. When the ropes caught I struck the wall back first with my head snapping back into the rock. When I hit the rock I sustained two injured ribs (not broken), a concussion, and whiplash. The helmet I was wearing is cracked but still in one piece. I lowered off and was helped back to the top of the crag as the concussion was making me dizzy and I had difficulty focusing on the scramble out. I rested for an hour before walking out whilst my friends retrieved the gear from the route.
