Cycling Fitness / Training Advice

Actually saw on the forum about red car training, basically, any time you see a red car on the road sprint for a minute or something, this will help produce random bursts of speed which can be helpful for road racing. Also as there are a fair few red cars about it should get you going in no time, or destroy you!

Could lead to a heart attack if you did this in London and included buses. There are all sorts of routines for interval training, a quick google brings up lots of different methods.
