Cycle racing

The Col de Porte is regularly used in the Critérium du Dauphiné. In the sixth stage of the 1977 Critérium, Bernard Hinault fell on the descent from the Col de Porte leading to Grenoble when he was alone in the lead, 1'40" ahead of his competitors. Despite the fall, he won the stage at Bastille in Grenoble ahead of Lucien Van Impe and Bernard Thévenet.[4][5]
