I fell for him. Not because I thought he could become a great rider but because I felt straight away that I could play a role in his life, that he needed me. Three years later we were married. Our dream had started. We didn’t know then that it would turn into a nightmare". Maertens rode his first race at Westhoek when he was 14, in 1966. The field included riders of 17 and 18, including some from France. The race was open to riders who did not have a licence from the Belgian federation, the BWB. He had trouble riding in a group. His second race went better. Among the riders he beat was Michel Pollentier, later a friend and a team colleague as a professional. Maertens continued to ride unlicensed races in 1967. In 1968 he took his first licence from the BWB, riding in the "nieuweling" or beginners' class. He won 21 times and came second 19 times to a rider named Vandromme. Maertens asked his father permission to leave school in his second year as a junior, or under-19, rider. He won 64 times as a junior. His father made him promise that he would train regardless of the weather. Gilbert Maertens gave his son his first bike, which Freddy Maertens described as "a second-hand thing that he’d got from a beach business for a bargain". Not until he won a race on that would he get a better one. The author, Rik Van Walleghem, said: "The training school that Maertens went through with his father was hard. Horribly hard. Gilbert never lost sight of anything. He knew how much and how often his son trained, what he ate and drank, how much he slept, who he went around with. He imposed a merciless regime. And he had an eye open for the slightest thing that would obstruct his son’s progress. He worried, for instance, that Freddy’s male hormones would get the better of his son and drive him into the arms of bewitching young girl who’d put the slides under his mission. Women were the devil’s work; it had been like that in the Garden of Eden and little had changed since". Gilbert caught his son flirting with a girl and took revenge by cutting his racing bike in half. He intervened with the army, when his son was called for national service, to ask that he not be given an easier time because of his reputation.
