Frankel and Black Caviar - the world's two highest rated racehorses - have retained their unbeaten records after racing at last week's Royal Ascot meeting. 

Frankel flies home

The Henry Cecil-trained colt stamped his utter authority on Ascot on the opening day, coming home 11 lengths clear in the Queen Anne Stakes.

Jockey Tom Queally didn't seem to even ask Frankel to find a fifth gear as he made a mockery of some seriously good rivals to cross the finish line alone, much to the delight of the Royal Ascot crowds.

Black Caviar gets it by a nose 

The highlight of the final day of the five-day race meeting was the Diamond Jubilee Stakes, featuring the Australian sensation Black Caviar. 

The mare - who was bidding for her 22nd consecutive win - had the expectations of the world on her shoulders, having been hugely impressive in all of her previous starts.

She gave her legions of fans a bit of a fright, however, when she only just held on to win by a short head from Moonlight Cloud. Afterwards it transpired that the mare had suffered some soft tissue damage and bruising.

For her to win a highly competitive race while injured shows just how superb Black Caviar is. A decision is expected as to whether she will race again, or be retired with her immaculate record intact.
