The L’Étape du Tour 2026 promises to be one of the toughest Étapes in recent memory. Covering 170 km with 5,400 metres of climbing, this high mountain sportive starts in Bourg d’Oisans and finishes in Alpe d’Huez via the Col de Sarenne. Having cycled, supported riders, and lived in the region since 2008, I’ve learned the real challenges these roads present. Over the years, pacing, fatigue management, and navigating tricky descents become just as important as conquering the climbs themselves.
