There is one interesting race spot on my commute. Coming off of the island at Hyde Park Corner onto the road down to Buckingham Palace is controlled by lights. Right now you get about six or seven cyclists strung out in a line just itching for the signal. The ensuing pedal mash is always quite enjoyable. It's a straight road on a clean, gentle downhill slope so good gearing is key. As it's close to work I get one last good thrash before parking up and chaining myself to the computer.
