The Gold Cup, inaugurated in 1807, is the historic centrepiece of Royal Ascot, staged on the middle day over an examining two-and-a-half miles (4-25). Some of the really outstanding Ascot memories have been created in the Gold Cup, in recent years by horses like Royal Rebel, Persian Punch, multiple winners Yeats and Stradivarius and by the mare Estimate, successful for the late Queen in 2013.
