Lots of people in Greendale have their own set of wheels. Ajay has his speedy motorbike, Alf drives a tractor, PC Selby uses pedal power, Ted Glen gets around in his lorry and, of course, Pat has his trusty post van. So Pat and Alf come up with the idea for a Great Greendale Race. When Mr Pringle waves the starting flag, Ajay zooms into an early lead but the race has some surprising obstacles...and the winner is a bit of a surprise, too!
