1. First ever time clip less. Waterloo roundabout, in the rush-hour, with about 500 spectators. Pull up at lights and gracefully topple onto my side. Just in case anyone hadn't noticed the cyclist with a bicycle on top of him, and needed their attention drawn to the sight, a police car pulled up alongside and put its blue lights on.
2. London to Brighton, on the trike. We were stopping at every other stop, but others from my group called to say they'd gone into the stop I was passing. No way to turn around against the stream of cyclists, and marshals wouldn't let me in the exit (not unreasonably). 'No problem,' I thought. There was just a four-foot grass bank separating the road from the school. 'I'll just take a run up at a 45-degree angle and cycle over the bank,' I thought. Cue cyclist upside-down with trike on top of him in front of hundreds of people.
3. Had the trike a few weeks, cornering faster and faster and being amazed at how stable it was round bends. Eventually the laws of physics reasserted themselves and I flip the trike. End up upside-down with a trike on top of me in front of a bunch of spectators.
You may be detecting a bit of a theme here.
