Pietro Bestetti was the brother of Angelo Bestetti, also a good cyclist, who competed briefly as a pro. But Pietro was the better of the two, competing six times in the Giro d’Italia between 1922 and 1931, with best finishes of sixth in 1926 and seventh in 1925. His biggest victory as a professional was the Tour de Lac Léman in 1923. He also rode nine times at Milano-San Remo, placing fourth in both 1924 and 1925. His best classic finish was runner-up at the 1925 Paris-Roubaix. Prior to his Olympic appearance, he won the Trois Vallées Varésines in 1919 as an amateur. Pietro Bestetti died fairly young from pneumonia.
