  Still a hidden gem, this 8 km climb features irregular gradients with ramps up to 9%, creating an early selection.

  A true Alpine classic, the Télégraphe rises for 12 km at 7% average gradient. A steady but demanding climb, it marks the gateway to the high mountains.

• Col du Galibier (2,642 m)
  A monument of world cycling, the Galibier stretches over 18 km from Valloire, with the final 8 km above 2,000 m altitude. Gradients rarely dip below 8%, with long, relentless ramps leading to the summit.
