The competitors climb up to the top of the almost-impossibly steep Cooper's Hill and chase a large not-quite-round wheel of double Gloucester cheese down to the bottom.

After the final race, candy is thrown down the hill for a children' 'scramble.' This has been attacked by children' charities as being highly dangerous, but has been praised by almost everyone else as being very funny.
