Cheers beardee, it wasn't a major crash, I was just going a bit too fast for my limited skills across a lava field, and fell on very hard and very sharp volcanic rock. I had elbow and knee pads on, but when I picked myself up, my left elbow pad was around my armpit and blood was flowing freely from my elbow, my left forearm, my left calf, and somehow my right ankle. Proper knarly riding! The bike tumbled a further 40ft or so than me, so it came off a bit worse! We were at over 2000m elevation after a hard climb from our uplift, which dropped us off at about 1000m, and were just starting our decent along a volcanic ridge back to sea level. The guide and the other 3 riders helped patch me up and straighten the wheel and mech enough for me to ride out. It would have been a long and hard walk back otherwise in the plus30 heat! Loved it though, and would love to go back in the autumn or winter, which is high season out there for mountainbiking, summer is just too hot. La Palma has some great trails with some spectacular scenery, but it is really challenging. Being one of the steepest islands in the world, it's all either relentless uphill, or steep and really technical downhill, and as you may gather, rocky as hell. My bike was seriously outgunned by the terrain, with 147mm travel at the rear, and 120mm up front, the other guys where on proper A/M hire bikes with dropper posts that had at least 150mm at both ends, and I spent a lot of time polishing the top tube with my nuts after my feet had been bounced out of my pedals
