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.^[5]

2014: Three-year-old season

Avenir Certain first start as a three-year-old was the Prix des Carrefours, a 1600m conditions race run on the polytrack at Chantilly on 9 April 2014. She started as a short-priced favourite and won by two lengths from runner-up Got Fly.^[5] Avenir Certain then contested the Group 1 Poule d'Essai des Pouliches. In the early stages of the race she was positioned near the middle of the 16-runner field by jockey Gregory Benoist. She drifted right in the finishing straight, but ran on to take the lead with about 200m left to run and pulled clear to win by one and a quarter lengths from Veda, with Xcellence a further two and a half lengths further back in third place.^[6] There was a stewards' inquiry into the result of the race for possible interference, but the placings were not altered.^[7]

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.^[8] 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.^[9]

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.
