It turns out spaces is more limited that i first thought. Having spoken to the very helpful guy now running the event, he has offered to allow us extra bikes but i need to let him have numbers by Friday.
As I've only had two people contact me so far i may end up with egg on my face
Please post here if you are interested in attending.
As i live within a few miles of Beaulieu i will offer floor space to anyone who may need it over the weekend
