St Leger Festival day three preview

Day three of the St Leger festival at Doncaster is headlined by the 250th running of Britain's oldest Classic, with the £700,000 Betfred St Leger (3.35) taking centre stage.

Aidan O'Brien is chasing another success in the race, having won the last three, and has assembled a formidable team headed by Derby winner Christmas Day, alongside Pierre Bonnard, Action and Amelia Earhart.

Joseph O'Brien looks to spoil the Ballydoyle party with Royal Ascot winner Enceladus, whose rapid rise through the ranks has made him one of the leading contenders, while Highwayman adds further strength to the Irish challenge. Andrew Balding also has a strong hand with Hatteen and Galiyan in the line-up.

The supporting card is packed with quality including the Group 2 Champagne Stakes (1.45), a race that regularly throws up future Group 1 performers and this year looks no different with the hot favourite Desert Castle representing Godolphin.

The Group 2 Park Stakes (3.00) provides another high-class contest as the William Haggas-trained More Thunder seeks his first win of the season.
