In October 2006 I got my first fixed, I am loving it and noticed that I was able to cycle faster and faster as I got used to the bike and was cycling more and more. I seem to have reached a plateau and was wondering if anyone has any tips for training, both ideas for how to ride and places/events to go to.

I ride about 12 miles a day, in London UK through the city center so there is lots of stop start riding and lots of trackstands, which I have noticed are quite a good work out, but don't make me go faster. I really only have time to do training rides at the weekend. I live by Brick Lane, so Richmond Park is a bit too far.
