Incarville made little impact on her racecourse debut as she came home tenth of the eleven runners in a contest for hitherto unraced juvenile fillies over 1500 metres on good to soft ground at Deauville Racecourse on 4 August. Nineteen days later at the same track she finished second to the Andre Fabre-trained Anasia in a maiden race over 1600 metres, beaten one and a half lengths by the winner. On 1 October the filly was ridden by Cristian Demuro in a maiden over 1800 metres at Compiegne and recorded her first success as she won by four lengths at odds of 3.1/1.[6] Demuro was again in the saddle four weeks later when Incarville started odds on favourite for the Prix de la Masseliere over 1800 metres on heavy ground at Longchamp Racecourse and won by a head from Benita.[7]
For her three-year-old debut Incarville was moved up in class and distance for the Group 3 Prix Penelope over 2100 metres at Saint-Cloud Racecourse on 6 April when she was ridden Christophe Soumillon and finished second of the five runners behind the odds-on favourite Philomene.[8] Over the same course and distance on 1 May she was partnered by Demuro when she finished second again, beaten one and a quarter lengths by Harajuku in the Group 3 Prix Cleopatre after leading for most of the way.[9] On 23 May the filly was moved up in class again for the Group 1 Prix Saint-Alary over 2000 metres on very soft ground at Longchamp in which she was ridden by Soumillon and started the 5.8/1 fifth choice in an eleven-runner field. Penja started favourite while the other contenders included Harajuku, Anasia, Rumi (Prix Vanteaux) and Cirona (Prix de la Grotte). Incarville was settled towards the rear of the field as Cirona set the pace, before beginning to make progress on the outside 500 metres from the finish. She maintained her run and reeled in the leaders before gaining the advantage in the final strides to win by a head from Cirona with Es La Vida another head away in third place.[10] After the race David Smaga said "Besides her first run when she was unplaced, this filly has never run a bad race and definitely has a preference for soft ground–there is no doubt about that. She has also improved with every run this season and is versatile regarding tactics. Christophe Soumillon gave her a great ride."[11]
Incarville was ridden by Gregory Benoist when she started a 21/1 outsider for the Prix de Diane over 2100 metres at Chantilly on 20 June. After being restrained towards the rear in the early stages she made steady progress in the straight but never looked likely to win and came home seventh of the seventeen runners, two and a quarter lengths behind the Irish-trained winner Joan of Arc.[12] On 24 June it was announced that Incarville had been bought by Katsumi Yoshida of Northern Farm.[13]
On her first appearance for her new connections Incarville was dropped to Group 2 class and finished fifth behind Rumi in the Prix de la Nonette at Deauville on 21 August after leading until the last 400 metres. In September she returned to Group 1 class and came home fifth of the seven runners in the Prix Vermeille at Longchamp, beaten almost five lengths by the winner Teona.[14] She ended her season in the Prix de l'Opera at the same track on 3 October when she finished eighth to Rougir.
