In a repeat of last season’s Arc, Criquette Head-Maarek’s brilliant mare had the Andre Fabre-trained entire back in second place as she recorded her fifth Group One success.
Treve was quite handy in about fourth place in the early stages, with the pace set by her stablemate Altaira until the latter ran wide into the straight.
Flintshire hit the front on the far rail, but Thierry Jarnet was wise to the move and ushered Treve (4-9 favourite) to go and win her race, which she duly did in relatively cosy fashion by a length and a quarter.
Dolniya was third without ever threatening to challenge for victory. Treve was cut to 5-2 favourite from 11-4 with Paddy Power to win the Qatar-sponsored Arc for the third year running on October 4.
The daughter of Motivator will now have a break before returning for her Arc prep in the Prix Vermeille at Longchamp on September 13.
Harry Herbert, racing advisor to owners Al Shaqab Racing, said: “Absolutely fantastic. That was really exciting. It just shows she’s as good as ever or better than ever because it was a very impressive performance on ground that was certainly quicker than ideal.
“She was a little bit free, but Thierry got her beautifully settled and she’s just a champion. The next stop is the Vermeille. It’s fingers crossed. Everything’s gone well so far and it’s been a great performance by Criquette. We hope now the plan can be executed. We’re halfway through the plan.”
Head-Maarek was understandably delighted with the latest superb display from her stable star.
She said: “It was fantastic. She won very easily, she just needed a tap to make her go.
“She’s a good filly. We don’t know what she’s worth really.
“The plan is to give her a break and then bring her back for the Vermeille.”
Jarnet said: “The ground was a little bit too firm for her, but it is said that the good horses will go on any ground.
“I didn’t really worry about the other horses, the leader did his job and there was a good pace. She quickened progressively without getting in the way of anyone. The mare was in great form, she is brilliant.”
Coral make Treve 2-1 favourite from 5-2 for the Arc, with Golden Horn 5-1 and Jack Hobbs 8-1.
Spokesman David Stevens said: “If anything Treve looks better than ever this season, and she is now 2-1 for an unprecedented Arc hat-trick, although with Golden Horn’s Derby victory getting a big boost with the Irish Derby result on Saturday, the mare will have to be at her best to make history at Longchamp in October.”
