Your nearest societies would be Lincs and Leamington, the latter hold regular training sessions.
I would suggest that you go and watch a Championship Working Trial either PD or TD handlers to get an idea of the requirements and standards, the nearest one to you is probably Stamford but that is not until July but there is one in Dunholm Lincs in March.
Turn up and you will find that everyone is very friendly and most competitors will not mind you watching them track if you ask first and the Control and Agility can be watched by anyone.
There is a taster workshop on tracking at the Learning About Dogs Centre on Jan 15 and some tracking days in March, April, May and June if that helps.

ps don;t take a dog onto the field though.
Most groups are self help ones and you may find it more useful to go to a 1:1 trainer, the best ones near you are around the Notts area
