[Kraftwerk] How to find out which route KW cycles to shows

I read in the BBC interview, I think, that they leave Ralf and Florian off 100 km from the concert destination and the ride their titanium bikes in from there. During the ride in software records their Electro Kardiogramm. Hey, if anyone knows the route they are taking, please post it to the list. I know they are intensely private about stuff like that, but that would be one heck of a vitamin-charged aerodynamik paceline!
