Treve ran out a brilliant winner of the Qatar Prix Vermeille at Longchamp.

The dual Prix de l'Arc de Triomphe heroine was beaten in this race 12 months ago, but there was never going to be a repeat as the Criquette Head-Maarek-trained mare proved in a totally different league to her rivals.

Racing in mid-division before making significant ground to go third entering the false straight, the five-year-old raced widest of all turning for home and once Thierry Jarnet asked her to quicken with a quarter of a mile to run, she showed a dazzling change of gear.

Arabian Queen, the shock winner of the Juddmonte International, was keen early on and while racing prominently for some way she had no answer to the principals at the business end.

Harry Herbert, racing manager for Treve's owners Al Shaqab Racing, said: "It's amazing the way she looks, and how much bigger she is this year.

"Then she puts in a special performance like that, when she was absolutely cantering over them.

"It's unbelievable the way she travels."

Head-Maarek said: "I really don't know what to say, but I would like to thank my team, who have done such an amazing job with her."

Coral go 10-11 (from 2-1) about the winner to claim an unprecedented third Arc on October 4th while Paddy Power have her at evens for the Arc (from 2/1).
