Intello's first race was in a 1600-metre maiden at Longchamp on 22 September 2012, which he won by a short-head. His only other race as a two-year-old was a conditions race at Maisons-Laffitte. He started as the odds-on favourite and beat Kapstadt by half a length to win the race.
2013: three-year-old season
Intello started his three-year-old campaign by travelling to England for the Feilden Stakes at Newmarket in April 2013. He was ridden by regular jockey Olivier Peslier and started as the 6/4 favourite. After taking the lead with two furlongs left to run, he pulled clear to win by lengths from King George River, who in turn was seven lengths clear of third-placed Gorly Awaits. His next start was Longchamp in the Poule d'Essai des Poulains, where he was third favourite in the betting at 7/1. Olympic Glory was the 3/1 favourite, with Style Vendome starting second favourite. In the early stages of the race he was held up near the rear of the field by Maxime Guyon. He made progress through the field, but got boxed in between 600 and 400 metres out, before being taken wide by Guyon, when he stayed on to finish third, less than half a length behind winner Style Vendome. Olivier Peslier was Intello's jockey again for the Prix du Jockey Club, for which he started favourite. Peslier positioned his near the front of the field and challenged with 400 metres still to run. He took the lead 300 metres out and pulled clear to win by two lengths from Morandi who just beat Sky Hunter to take second place. In July he dropped back in class for the Group 3 Prix Messidor. Starting as he short-priced favourite, he took the lead inside the final 200 metres and won the race, beating runner-up Mainsail by a length and a half. In August Intello dropped back in distance for the Prix Jacques le Marois at Deauville Racecourse. In a very competitive field ran third to Moonlight Cloud and Olympic Glory, finishing ahead of Declaration of War, Dawn Approach and Elusive Kate. On 21 September, Intello prepared for a run in the Prix de l'Arc de Triomphe by winning the Prix du Prince d'Orange over 2000m at Longchamp. In the Arc on 6 October, Intello started at odds of 10/1 in a field of seventeen runners. He was among the leaders from the start and eventually finished third, beaten five lengths and a neck by Treve and Orfevre.
