Frankel could face his toughest test in the final race of his illustrious career as he and triple Classic winner Camelot head the entries for the Qipco Champion Stakes at Ascot on October 20th.
The high class pair are among 46 horses entered for the 1m 2f Group 1 which was won last year by Cirrus Des Aigles.
Aside from Camelot, Aidan O’Brien has entered the likes of St Nicholas Abbey, Imperial Monarch and Power.
Rod Street, chief executive of British Champions Series Limited, said at the announcement of the entries: “We could not have hoped for better entries and they set the second edition of Qipco British Champions Day up to be a ‘must-see’ event like last year’s.
“Frankel’s final racecourse appearance will, of course, crown the day and he could face his biggest ever test in the Qipco Champion Stakes, while his likely absence from the Queen Elizabeth II Stakes should make Europe’s richest mile race an ultra-competitive affair.”
