Alain Moineau had a good start to his amateur cycling career when he finished 11th in the road race at the 1948 London Olympics to help France to win bronze in the combined team event. Later that same year Moineau then finished third at the Tour du Lac Léman in Switzerland, before turning professional by the end of the decade. He went on to win stages at several races in the early 1950s, including the Tour de Luxembourg, and had two top-ten finishes at the Milan-San Remo one-day race. In 1950 and 1952 he rode in the Tour de France but abandoned the race on each attempt. Moineau’s father, Julian, had who won three stages of the Tour de France between 1928 and 1935.
