The Col du Tourmalet... a pass that was a real challenge for me! It climbs continuously for 20 km without any real respite... With the end getting a bit tougher, especially mentally!

Octave Lapize, the first to climb it on a bike during the tour. Check out the history, it's unmissable.

A charming town that's home to some of the Tour's iconic climbs. Stop and take a few photos of your bike in some of the picturesque spots you see.

One section is a private road with a barrier. We took it, but three large trees are across the path.
