Dual Prix de l'Arc de Triomphe winner Treve is a confirmed runner in the Prix Corrida at Saint-Cloud.
The five-year-old mare will have eight rivals on Friday as she makes her much anticipated seasonal return in the Group Two race.
She has been pleasing trainer Criquette Head-Maarek in the lead-up and will be ridden by her regular jockey Thierry Jarnet.
Stablemate Silvaplana is also among the declared runners.
Among their seven rivals are two from Andre Fabre's stable, Feodora and All At Sea, while Head-Maarek's brother, Freddy Head, will be in opposition with We Are, winner of the Prix l'Opera last season.
Completing the line-up are Cocktail Queen, Mayhem, Makruma and Siljan's Saga.
