ニエル賞
On 5 October, Avenir Certain moved up in distance to contest France's most prestigious race, the Prix de l'Arc de Triomphe over 2400 metres at Longchamp and started the 6/1 second favourite. She was ridden for the first time by Christophe Lemaire as Benoist rode the Prix Niel winner Ectot. She was among the leaders from the start and took second place in the straight but faded in the closing stages to finish eleventh of the twenty runners, six lengths behind the winner Treve.
