Czechoslovak cyclist Petr Hladík started competing in the youth category when he was 14-years-old. A few years later Hladík won the junior edition of the Peace Race in 1966, followed by the Prague–Karlovy Vary–Prague amateur race one year later. In 1968 he won a stage of the Tour of Slovakia and was selected to ride in the road race at the Mexico City Olympics, but did not finish due to a puncture. After the Games he became the Czechoslovak amateur road race champion, in addition to competing in the road race at the World Championships. Hladík continued to compete for several years, winning stages in races in Italy and Morocco, as well as the overall classification at the Tour of Serbia in 1972.
