I haven’t been able to contact the event organisers, but did manage to find one of the organisers of pervious Bucket and Spade Runs who told me it is a fairly informal event and if you want to enter a vehicle just turning up is fine.
Update I have been in contact with the event organisers, if you want to take part in the run you nee to get your old vehicle to
Brogdale Apple farm Near Faversham by 9am on this Sunday 5th June 2011.
