The Col de la Madeleine, between the Tarentaise and Maurienne Valleys, can be reached via three roads, all of which feature in the list of the area’s 15 most difficult climbs.
The road has been fitted with kilometre posts for cyclists.
The Madeleine is a true cycling legend, having featured in the Tour de France 25 times since the war - more than any other pass in Savoie.
