Hope the guy is ok.
Last summer on a club ride we had to stretcher a lad out. He took a very low speed tumble, and landed with his chest on the end of his bars (not even moving fast enough to over the bars)! Once the paramedics turned up, very speedily, considering the directions we had to give, they decieded that the air ambulance was needed but as we were in the woods we'd have to carry him out – about a mile, as to wait for mountain rescue would take too long. Mr paramaedic asked for volunteers, and i foolishly said yes and made some comment about having carried stretchers before on courses for mountain rescue teams, so he kindly informed me that I was to go in the middle, opposite him, as we would walk either side of the singletrack in the heather and he wanted an experienced(!)strecher bearer there. As he was also carying oxygen etc that our buddy was hooked up to, we weren't allowed to swap sides like the others could. Until you have tried it, you simply can't beleive how heavy a 15 stone man gets! It took us an hour to covern that mile.
We then had to sit and wait for a further 30 mins watching the air ambulance fly around over the wrong valley!
