Early in my commute, some bloke on an olive single speed bike drifted lazily through the red light where I had stopped and vanished into the distance. Several junctions later, he caught up with me at another set of lights, just as they went green. I passed him as we entered a minor road that's a short cut through an estate and had forgotten about him by the time I approached the second corner and took it at speed...
Black ice on smooth road surface, rear wheel skids uncontrollably, thigh slams into road and I'm rolling, bike in air above me, stand up, am holding bike though have no memory of grabbing it, nod of relief to RLJer who has slowed to enquire about health, look over bike, remount and pedal. Realise that something is poking me in the thigh where nothing has poked me before, look down and realise saddle was rotated 30 degrees by the impact, dismount and fettle. As I do this, I see somebody else take the corner and also come off her bike - not as badly, since she wasn't moving as fast. The cyclists behind her have the benefit of her example and, since she stayed at the corner while gathering herself and her possessions, so did the cyclists behind them.
When I made the turn from Prince of Wales Drive onto Battersea Park Road, another slow moving RLJer sailed slowly out from the opposite direction and, despite having had plenty of time to clock me, cut right in front of me as he crossed towards the park. I was not polite.
Very mild grazing on right thigh, but I tore a small hole in the shorts.
