1954 two-year-old season In 1954 Ribot began his racing career by winning the Premio Tramuschio over 1,000m at
San Siro Racecourse by one
length. He then won the
Criterium Nazionale over 1,200m at the same course by two lengths. He ended the season by running the
Gran Criterium over 1,500m at San Siro. In this race Camici attempted to ride a waiting race and Ribot won narrowly by a head from Gail. In all his subsequent races he either led from the start or raced close to the leaders.
1955 three-year-old season Ribot had been unusually small as a
yearling, being nicknamed "il piccolo" (little one). As a result, he was never entered in races such as the
Premio Parioli and the
Derby Italiano. In 1955 Ribot won the Premio Pisa at Pisa Racecourse by six lengths and then took the
Premio Emanuele Filiberto at San Siro by 10 lengths. After a break to allow the colt to recover from a respiratory illness he won the Premio Brembo by one length from Derain, and the Premio Besana over 2,400m by 10 lengths, again beating Derain, who won the
St Leger Italiano two weeks later. In October he raced outside Italy for the first time when he contested the
Prix de l'Arc de Triomphe over 2,400 metres at
Longchamp Racecourse. Starting at odds of 9/1 he took the lead early in the straight and won by three lengths from
Beau Prince. According to press reports, he won very easily, with Camici never resorting to the whip and restraining the colt rather than driving him out in the closing stages. After the race he was surrounded by photographers and given the attention normally reserved for Hollywood film-stars. In his final start of the year he returned to Italy, where he won the
Gran Premio del Jockey Club by 15 lengths from the previous year's winner Norman on heavy going.
1956 four-year-old season Ribot began his four-year-old season with three easy wins at San Siro. He won the Premio Giulio Venino over 2,000 metres by four lengths, the Premio Vittuone over 2,400 metres by twelve lengths and the Premio Garbagnate over 2,000 metres by eight lengths from Grand Rapids. He then contested Italy's Premier
weight-for-age race, the
Gran Premio di Milano, then run over 3,000 metres, at the San Siro. He led from the start and won by eight lengths from Tissot. Ribot then returned to Milan, where he won the
Premio del Piazzale over 1,800 metres, winning by eight lengths from a field which included the Premio Parioli winner Magabait. In October, Ribot returned to Paris for his second Prix de l'Arc de Triomphe. He faced a stronger field than in 1955, with the field including
Talgo (
Irish Derby),
Tanerko,
Fisherman,
Career Boy,
Master Boing (
Washington, D.C. International) and
Oroso. Ribot took the lead on the turn into the straight and drew away from the field to win by an official margin of six lengths from Talgo. Photographs suggest that the winning margin was more like eight and a half lengths. ==Stud record==
