Criquette Head-Maarek has confirmed her incredible Prix de l'Arc de Triomphe heroine Treve will stay in training as a four-year-old to defend her Longchamp crown.

Hugely impressive in the Prix de Diane and the Prix Vermeille, the Motivator filly completed the Group One hat-trick with a truly stunning display against the colts in Europe's premier middle-distance prize.

A trip to Hong Kong later this year is still under consideration, although far from certain, and Head-Maarek is already dreaming of back-to-back Arc victories in 12 months' time.

"I am with her in the paddock now and she looks beautiful. She ate up everything last night and hasn't lost any weight. She is just an amazing filly," said the trainer.

"She won the race very easily. They pushed her to the outside but when she came there in the false straight, I knew she was going to win.

"I know Thierry Jarnet's riding very well, I could see he had a lot of horse underneath him and when he let her go, they were never going to catch her.

"It's her turn of foot that is so unbelievable. When you look at the times, she ran the last 400 metres faster than the winner of the Prix de l'Abbaye and the Foret, which is incredible after a long-distance race like the Arc.

"She will stay in training next season and I don't think we will run her again this year.

"If she does have one more run, it will be in Hong Kong as the Breeders' Cup is too close and the ground in Japan is always very hard.

"Sheikh Joaan (Al Thani, owner) bought her to win the Arc and she did it and now we have to try to win it again next year.

"She will run in the spring and even though she stays the distance (mile and a half) well, she has so much pace she could easily run over 2,000 metres (mile and a quarter) or even over a mile. She can do everything."

"She will stay in training next season and I don't think we will run her again this year" - Criquette Head-Maarek

Treve is the latest in a long line of top-class horses trained by Head-Maarek, who was already the only woman to have trained the winner of the Arc thanks to another filly, Three Troikas, back in 1979.

The Chantilly handler is not keen on comparing horses from different eras, but admits Treve has to be ranked high in the list of thoroughbreds to pass through her hands.

"It is hard to compare as it is a different year, but she has to be one of the best fillies I have trained," said Head-Maarek.
