I'm going to own up to being pretty badly prepared...I carry nowt with me. Only stuff in my camel back is sqaush, few energy bars including an emergency gel, multi tool, tool for my Cane Creek shock, tyre levers, patches, spare tube, mini pump and a shock pump. On wetter days I'll take a gillet or a jacket with me. When I'm riding locally, I don't even take this...just my phone and car key.
My lack of preparation was shown up a couple of weeks ago though. I was in Hopwas on a Sunday morning and bumped into two guys who I needed up riding with. I showed them a line that they'd not ridden before. Nothing too major; short run of three jumps and a table top at the bottom.
Everything was hunky dory, we all did a couple of runs then one of the guys blew his tyre off is rim. Fixed it so we thought we'd have one last run before moving to a different one...this didn't go so well.
The guy who had been having issues with his tyres pinned the line and overshot the landing for table top...big time. He put his front wheel down as if to hit the landing but he was so far past it that he nose wheelies into a nearby tree at high speed with most of the impact going through his head / neck.
Almost immediately it was apparent that he was in a bad way complaining about his neck – his full face was toast. The other chap and I managed to get his bike untangled from him without moving him. We called an ambulance but only I knew where we were so directed agreed to meet the ambulance at the nearest main road. I met the crew and helped them carry their stuff in to him. By the time we got there he was in a bad way; white as a sheet, shivering, struggling to take deep breaths and in a lot of pain. As riders we had naff all to put over him to help keep him warm.
The ambulance crew tried to arrange for an air ambulance when they realised that he was pretty badly injured but there was nowhere suitable for it to land. Another crew were dispatched who I had to go and meet and guide in. A specialist crew were then sent with an offroad buggy (they described themselves as the ground version of the air ambulance) to retrieve him.
All of this took a fair amount of time - but the crews were fantastic (two of them were MTBers so were not surprised, but gave us some stick for mucking about on DH stuff). The chap is OK - four broken vertebrae but will walk / ride again.
I often ride on my own and have ridden this line so many times - not sure what I would have done if I had been the injured rider and was on my own. It does make you think a bit - all of this was no more than 15 minutes from the main road but the lines there are generally quite hidden.
I think I'll be rethinking my lack of first aid equipment (not that it would have helped much in this situation - but it would have helped my knee when I came off at Cannock the other week. Cleaning a deepish hole in my knee up after finishing my ride was pretty painful).
