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!

Ascent to the summit on foot; no cable car access until 2027. No access to the restaurant or restrooms, but drinking water is available.
