The Col du Berthiand is a mountain pass rising to 780m (2,560feet) above sea level, situated on the Montagne de Berthiand in the Jura mountains. It is located in the department of Ain in France and joins the commune of Serrières-sur-Ain with Nurieux-Volognat.
The name, like those of the Montagne de Berthiand and the hamlet of Berthiand originate from Bertoldingos ("with the Bertoldingi") derived from the family name Bertoald.[1]
The Tour de France has traversed the Col du Berthiand on four occasions, the last being during the 2016 Tour de France, with Rafał Majka first over the top.[2] [3] [4] The riders who crossed in the lead are shown in the table:
