Starting in Saint Michel de Maurienne at 730m with it’s summit at 1566m it’s seen as the warm-up to it’s bigger brother, Col de Galibier, but the Télégraphe deserves more than that.
With a maximum gradient of 9.9% it’s not to be taken lightly, especially if you are following it with the short descent into Valloire and the ascent of the Galibier. On top of that it can be very hot in the Maurienne valley in the summer so it can be tricky from the first kilometre.
Preceding the Galibier in the Marmotte Sportive which takes place every July it’s a climb we ride several times over the summer during our Alpine Weeks.
The Tour de France will descend the Télégraphe in stage 19 starting in Valloire.
