Triple Crown-seeking Camelot is set to work between races at Leopardstown on Thursday.
The Montjeu colt has won the 2000 Guineas, Derby and Irish Derby in an all-conquering season so far, and trainer Aidan O'Brien has now set his sights on next month's Ladbrokes St Leger at Doncaster.
Next week's Great Voltigeur Stakes at York had been considered as a possible prep for his date with destiny, but the Ballydoyle trainer has instead opted to go for a racecourse gallop.
O'Brien had initially planned to give Camelot a spin between the first and second races, but due to logistical issues, he will now work before racing starts.
O'Brien said: "We are delighted that the Irish racing public will have the opportunity to see Camelot before he runs in the St Leger at Doncaster.
"We would like to thank the clerk of the course, the stewards of the Turf Club and everyone at Leopardstown for allowing it to happen."
Leopardstown chief executive Pat Keogh is pleased to accommodate O'Brien's request, with his racing career having started at the Dublin track.
He said: "We are delighted to see Camelot return to Leopardstown where he won his maiden last July.
"We've watched him with great pride as he became a great champion."
Should Camelot land the Doncaster Classic on September 15, he will become the first horse since Nijinsky in 1970 to claim the colts' Triple Crown.
