List of teams and cyclists in the 1970 Tour de France

After his dominating victory in the previous year, Merckx was the major favourite for the 1970 Tour de France. The main competition was expected from Luis Ocaña and Bernard Thévenet. Early in the race, 86 journalists predicted who would be in the top five of the Tour. 85 of them expected Merckx to be in the top five; Ocana was named by 78, Poulidor by 73. Merckx had already won important races in 1970, including Paris–Roubaix, Paris–Nice, the Giro d'Italia and the Belgian national road championship. Luis Ocaña, who had won the Critérium du Dauphiné Libéré and the Vuelta a España, suffered from bronchitis, but still started the Tour, unable to seriously challenge Merckx.
