I made sparks!
We'd stopped off to help a friend who'd had a p*nct*re. I didn't stow my pump properly, so, when I was heading home at 32kph, the hose came loose, and was in danger of catching my left foot/crank etc. As I tried to clear it away, I drifted to the gutter, and my pedal struck twice. Apparently, it was quite interesting from behind.
Fortunately, the kerb was only just higher than my pedal's bottom position, so I just got a couple of shoves before I could break free.
