Cycle Training

But is it ok to undertake cyclists? That was not covered at all in my cycle trainings. We covered how to behave with cars etc but not with other cyclists.

It's not OK to undertake other cyclists. As skydancer said, the way to deal with it is to check for their presence on your left. When he trained me, he sneakily undertook me on the left round a corner. That was the first time that I'd ever been undertaken by a cyclist--I simply hadn't been aware of the fact that people do this (despite having paid attention to my primary positioning since reading a London Cyclist article on Cyclecraft in 1998 or 1999).

Since then, it's happened to me once--or, rather, twice, by the same person in the space of about five minutes. I was riding along Newgate Street on a lovely sunny afternoon/early evening, when this bloke on a bizarre but expensive-looking hybrid suddenly dived along the inside of me, spinning madly in a really low gear. There was absolutely no need to go down the inside, as there were no cars in the vicinity. I overtook him again and at Holborn Circus made to stop at the kerb next to that Sainsbury's building. I checked back over my shoulder and looked at him and he was too far away to still reach me, or so I thought. As I slowed down, signalled with my hand and put my foot out to stop, he must have accelerated as he lunged past me on the inside again, with inches or centimetres to spare. That was a near-crash and I think that this time he simply wasn't paying attention. He seemed like a new cyclist, didn't know what gear to use, etc.
