"As a rule of thumb, British testers used to take a urine and breath sample of each jockey at least once a year but, among jockeys at least, there is a feeling that this has been upped this year. A minimum of one racecourse a week is selected by the testers and at it every jockey is breath tested – the threshold for alcohol is half what it is for driving – and a dozen will provide a urine sample from a random draw."
