Amateur Bicycle Racing outside of the US I'm interested in taking a trip to Europe (although perhaps this question can apply to other areas of the world) and do some bike racing at a really amateur level like the equivalent of Cat 4 or Cat 3 in the US.  Mainly interested in road races.

Any ideas on where I can find information on these types of races if they exist?  Also any tips on administrative details of racing as a foreigner are appreciated.
If you are coming to the Uk then the British Cycling website is probably the place to start.
