There was yet another victory for France in the Queen Elizabeth II Stakes at Ascot as Big Rock delivered a devastating display on Qipco British Champions Day.

Often the bridesmaid when racing at the highest level this year, the son of Rock Of Gibraltar had finished second in the Prix du Jockey Club, Prix Jacques le Marois and Prix du Moulin in his last three starts.

However, Christopher Head’s brilliant colt finally got his moment in the spotlight, making every yard in the one-mile Group One feature.

Immediately taking his customary position at the head of proceedings, his rivals were left chasing shadows as big-race jockey Aurelien Lemaitre kept upping the tempo.

Having built up a healthy lead, it was Dermot Weld’s Tahiyra who decided to break cover from the pack first, with Chris Hayes setting the Irish 1,000 Guineas heroine in pursuit.

But there was no catching Big Rock (5-1) who kept on galloping in the rain-softened ground to register an emphatic six-length success and also lead home a French one-two, as Jerome Reynier’s Facteur Cheval stayed on past a tiring Tahiyra in the dying strides to grab the silver medal.

Short-priced favourite Paddington beat only two home, one of those being 2000 Guineas hero Chaldean.

Big Rock will bid for Group One glory in the Prix Jacques le Marois at Deauville on Sunday.

The Christopher Head-trained Rock Of Gibraltar colt has had a superb season so far, starting off with a wide-margin handicap success before progressing up the levels in a three-race winning streak.

The first leg of the hat-trick was the Listed Prix Maurice Caillault, which he won by four and a half lengths, after which he took in the Group Three Prix la Force and was a comfortable winner again.

At the same level he landed the Prix de Guiche by an unchallenged three lengths and the following month he stepped up to an extended 10 furlongs for the Prix du Jockey Club at Chantilly, running a huge race from the front before Arc favourite Ace Impact ran him down.

Another big-race tilt now awaits for the three-year-old, back to a mile against the likes of Kevin Ryan’s Queen Anne winner Triple Time.

“He’s going to run on Sunday at Deauville, everything is all right with him,” said Head.

“He is in good form and we are pretty optimistic about his run in the Jacques le Marois.

“He has been working well and we are looking forward to having another Group One run with him.

“He takes his racing very well and is a very nice horse.”
