In 2013 the recognised trials races have been dominated by Irish trainer Aidan O’Brien’s Derby contenders.
In mid-April Battle Of Marengo won the Ballysax Stakes over 1 mile 2 furlongs at Leopardstown and O’Brien has subsequently won the Chester Vase (1m 4f 110y) with Ruler Of The World, the Dee Stakes (Chester) (1m 2f 110y with Magician, and the Lingfield Derby Trial Stakes (1m 4f) with Nevis.
Later this afternoon Battle Of Marengo will contest the Derrinstown Stud Derby Trial Stakes at Leopardstown, which will reveal more about his Derby credentials.
Still to come next week is a key Derby trial in the form of the Dante Stakes at York (1m 2f 110y).
Of course, winning the trials does not mean you win the Derby and there is certainly a question about the quality of competition in the trial races and the relevance of Derby trials in the modern racing calendar.
Despite all of these winners for Aidan O’Brien, Jim Bolger’s Dawn Approach, winner of May’s 2000 Guineas at Newmarket, remains 13/8 favourite with William Hill for the Epsom Derby.
