The £200,000 Racing Post Trophy, staged at Doncaster on Saturday, October 28, has attracted 114 entries - with Aidan O'Brien having an amazing 32 of those.
The mile contest for two-year-olds frequently provides Classic clues for the following season and is the final Group One race of the British Flat turf season.
Since the turn of the century, three future Derby winners have landed the Racing Post Trophy in their juvenile season - High Chaparral (2001), Motivator (2004) and Authorized (2006) - while the 2002 victor Brian Boru went on to claim the St Leger at Doncaster in 2003.
O’Brien has won the race five times, including in 2009 with St Nicholas Abbey, and among his 32 entered is next year's current 2000 Guineas favoruite Zoffany.
Richard Hannon has carried all before him with his juvenile runners this season and he has entered King Torus, successful in both the Group Two Superlative Stakes at Newmarket and the Group Two Vintage Stakes at Goodwood, and also General Synod, owned by the Queen, who is an unraced Invincible Spirit colt from the family of Group One scorer Right Approach.
