The blue book runs are what you need to learn in order to become a London taxi driver, there are 320 runs in the blue book but you need to learn more than that. The runs are just a guide, you need to and will learn the whole of the 6 mile radius. What is the 6 mile radius? it’s exactly what it says on the tin, it’s a six mile radius from Charing cross.
Why are they called blue book runs, simply because when you apply to become a London taxi driver the P.C.O or Public Carriage Office will issue you with a little book that has a list of all the runs and yes it’s blue. Although this little blue book lists all the runs it doesn’t actually give you the run so what you would have to do is either work out the shortest route for yourself and then go and do it so you learn it or you get a copy of the taxi runs that have already been done for you. You would still have to go out and do the runs as that is the only way you will learn London. Below is an example of doing a run, this is the first run in the blue book, Manor House to Gibson Square:
You would need to do the whole of the blue book which consists of 320 runs, but remember when you are on your appearances you can be asked to take them from any point to any point within that six mile radius. You can get a copy of the runs Here
