The form a hill climb takes is...
Road is closed to all traffic, one bike is released at a time, races to the 'finishline' and the time it took is recorded.
All competitors take a turn, and then as a group return to the start area for another go-round. Depends on numbers attending, but there'd be 6+ runs each. There is the kudos of the best time, but really the aim is for each rider to improve their own times as the day progresses.
