I did the run for the first time last year and while there were some cracking bikes there, they have a catagory called 'friends of the wolds run' which is open to pretty much everything. i got the impression that while the classic stuff was the main event, they were happy for anyone else to tag along as long as they paid the £8 entry to charity. I'm booked to start with the XBR, but i may go on my little Suzuki GN250 as there aren't many places where the XBR gets out of third or fourth!
I don'tknow this years route, I'm guessing they change it slightly each year, but i think they usually have stop halfway round at 'The green Man , at Scamblesby just down the road from cadwell park.
May see you there
