Leopardstown racegoers will be treated to a view of the Triple Crown-seeking Camelot as he works before racing at the track on Thursday.
The Aidan O'Brien-trained colt already has the 2000 Guineas, Derby and Irish Derby in the bag this term and victory in next month's Ladbrokes St Leger at Doncaster would seal his place in the history books.
Nijinsky was the last horse to win the colts' Triple Crown back in 1970 and Camelot is a hot favourite to repeat the feat.
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."
According to the O'Brien camp, Camelot is due to work 45 minutes before the first race, which is due off at 4.50pm.
The trainer's wife Annemarie had initially announced he would work between the first two races, but logistical issues have seen the time adjusted.
She tweeted: "Slight change of plan, Camelot will now work 45 minutes before the first race at Leopardstown tomorrow. Apologies for any inconvenience caused."
