2013: Two-year-old season Avenir Certain faced only two opponents in her racecourse debut, which took place on 8 October 2013 at Bordeaux Le Bouscat Racecourse. She was ridden by
Jean-Bernard Eyquem and won race by two
lengths from Helwan. Her only other race as a two-year-old was a
conditions race at
Chantilly, the Prix de la Grande Folie on 31 October, which she won this race by one length from Felcine. There was a stewards' inquiry into the result of the race for possible interference, but the placings were not altered. In the
Prix de Diane, she was held up near the rear of the field by Benoist. In the finishing straight, he pulled her wide of the rest of the field and she stayed on to challenge with about 100m left to run. She won the race, having pulled one length clear by the finish. Amour A Papa finished in second place, with Xcellence third and Shamkala fourth, all of which finished within half a length of each other. On 19 August, Avenir Certain started 3/5 favourite for the Group Two Prix de la Nonette over 2000 metres at
Deauville Racecourse. She extended her unbeaten run to six, taking the lead inside the final furlong and winning easily by one and a half lengths from her stable companion Crisolles. 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. ==Breeding record==
