The bike, by the way, was fine.
I knew you lot would be concerned about this element
The rider is fine by the way. Broken eye socket, nose and jaw. As was mentioned, he went to jump something he should have rolled [indeed was told to quite clearly by about 6 other riders] and did the classic panic face plant. However, we all read about these things, but the reality is very ugly. He was in a very bad way and it took over two hours for the paramedics to get him off the hill. For all of those two hours he didn't really have a clue what had happened to him or why.
Can't say it's put me off cycling. Stuff happens.
I'm guessing my key point is that really if you are going out, to make sure at least one member of your group is carrying a basic first aid kit including one of those foil blankets. Those blankets are only £2 and weight nowt. We were 200m from the pub, but it still took over two hours to get him out, and that was with four ambulance crews in attendance. The blanket plus putting his arm in a sling made all the difference. As did telling him he was fine and to sit still and not move.
It's a great trail by the way, real class.
