Dubai is set for the biggest and richest night in horse racing, with some of the sport’s most famous horses, jockeys and trainers in action. $30 million (AED 110 million) in prize money are spread across the nine races which take place at Meydan racecourse. Last year’s Dubai World Cup winning jockey William Buick concedes he faces a real battle to return to the winner’s enclosure tonight. Buick saddles Godolphin hopeful Frosted who impressed with victory in the Round 2 Al Maktoum Challenge last month. He makes a step up in class for the $10 million showdown though and Buick is mindful of one challenger in particular.
