Linked below (I hope) is the information pack for this years GM. It has all the information you should need, including the rideout route but any questions please just ask.
Please do read it as it has information on how to buy your lunch (important to keep the belly happy!) and information on how the marker system will work on the rideout, which you will be a part of (otherwise you all go in different directions).
Also attached should be ITN and GPX files for your TomTom and Garmin sat navs respectively.
So sorry I can't be there myself, but next year!!
Have a great time!
