Agh, sorry to hear that guys, they sound pretty nasty

I came off too of course - slid the front wheel right across a root and hit the deck. Fortunately it was into soft stuff and I didn't get impaled by the bike
Saw a pretty spectacular crash in the middle of a fireroad stretch of all places. I think a guy was trying to get an energy bar out of his pocket. I guess he knocked the bars and turned his front wheel 90 degrees. We were all ticking along at a fair old pace so this poor guy did a massive cartwheel - bike in the air and everything! Amazingly he got away with it and seemed fine!
