In 1929 Mick the Miller won the Spring Cup competition here over 525 yards and then finished runner up in the Stayers Cup over 600 yards. The Irish Coursing Club issued a new list of classic races in 1932 and controversy followed because Harolds Cross was given the Oaks and not the Derby. Shelbourne had been given the premier event which did not go down well based on the fact that they had introduced the event. One year later and Harolds Cross were furious that Shelbourne were issued the race again. In a meeting Mr Tynan representing the track, had pointed out that the previous year Paddy O’Donoghue had promised that they could hold the event in 1933. I.C.C chairman John Bruton explained that they could not cancel a ruling by the club already made. Tynan stormed out and Harolds Cross refused to run any classics or their qualifying races and threatened to run their own Irish Championship. Finally in 1934 they were granted permission to run the Derby as long as they contributed a minimum of £100 towards the event. The ICC added a further £50 and it was also agreed that Shelbourne and Harolds Cross would run the competition in alternate years.
