Many of the best racehorses from Britain, Ireland & Europe flock to Ascot for British Champions Day.
The stellar seven-race card is the most lucrative day in British racing and will stage five Group 1 races, including the Champion Stakes.
A total of £1.3m in prize money is up for grabs in the feature race where Calandagan and Ombudsman will lock horns for the second successive year. Bay City Roller will also line up after his brilliant second in the Arc, with Aidan O'Brien opting to send Constitution River to the 10-furlong contest.
Each and every race will be shown live on Sky Sports Racing, with Sky Go also offering live streaming of the event.
ITV1 will also show TV coverage of the card in full.
All seven races from Ascot can also be watched via bet365's horse racing live streaming service.
