Schedule of all racing in the UK?

[Félix]

I'm about to move to the UK for a year (I'm excited!) and I'm planning on going to the races like I never could before (I'm from Canada). I'm having a hard time finding a schedule covering all the racing I could see (it's alright when I'm looking for the BTCC or other high profile series but club racing and anything below BOSS is hard if not impossible). If such calendars exist, can anyone link them?

I would also like to know what tracks are reasonably close/accessible from Birmingham (where I will be working). Donington and Silverstone look kinda close but it's hard for me to imagine exactly how easy it can be to get there since I have never lived in he UK.

Thanks in advance!
