The Col du Tourmalet is the most iconic climb in cycling. At 2,115 metres, it has featured in the Tour de France more than any other pass, crowning legends since 1910. This guide covers everything you need to know to conquer it yourself.
The Western Approach: Luz-Saint-Sauveur
The classic western approach from Luz-Saint-Sauveur covers 19 km with an average gradient of 7.4%. The climb starts gently through the valley but ramps up significantly after La Mongie, with sections reaching 10-12% near the summit. Plan for 1.5 to 2.5 hours depending on your fitness.
The Eastern Approach: Sainte-Marie-de-Campan
The eastern side from Sainte-Marie-de-Campan is 17.2 km at 7.3%. This approach is slightly shorter and more consistent, with fewer extreme ramps but a steady grind all the way to the top. Many cyclists prefer this side for its rhythm.
Tips for Success
Pace yourself — the final 4 km are the hardest. Bring plenty of water and nutrition, as there are no services between La Mongie and the summit. Check the weather forecast, as conditions can change rapidly at altitude. And don't forget to take a photo with the Geant du Tourmalet statue at the summit!
