Newmarket's Future Champions Day is to be moved to the Friday before British Champions Day at Ascot in 2014 to create a 'champions weekend'.
The move will see six Group One events take place in just 24 hours, with 4.5 million pounds in prize money up for grabs.
In another boost Ascot's Fillies' And Mares' Stakes on Champions Day has been upgraded to Grade One status.
Future Champions Day will now see three Grade One races, the Dewhurst, the Fillies' Mile and the Middle Park supported by the Challenge Stakes, the Cornwallis (which has been moved from Ascot) and the Darley Stakes.
Newmarket supremo Amy Starkey said on the track's website: "British racing and Jockey Club Racecourses have decided to move Dubai Future Champions Day to a Friday in 2014 in order to create a 'Champions Weekend' alongside QIPCO British Champions Day at Ascot Racecourse.
"This is good news for Newmarket Racecourses.
"Becoming part of the 'Champions Weekend' means that Dubai Future Champions Day, including the Dubai Dewhurst Stakes whose home is at Newmarket, will increase its status as Europe's two-year-old championship day by featuring three Group One races for the first time in 2014 as part of a superb two-day climax to the Flat racing season."
