The Clerk of the Scales is required to ‘weigh in’ the riders of the winning and placed horses, and where extended prize money is allocated, as well as any other riders that he chooses to weigh in at his discretion. When the Stewards and the Clerk of the Scales are satisfied with the result of the race, and all riders have weighed in as required, the ‘weighed in’ announcement will be given over the public address system and winning bets may be collected.
