Famous road climbs in France (Tour de France climbs such as Alpe d'Huez, Mont Ventoux, Col du Tourmalet and Col du Galibier) with length, average gradient and, where stated, maximum gradient, elevation gain, summit and start altitude. Figures come only from official sources (race organisers, tourism offices, municipalities or road authorities), one per climb, named and linked in every row with the date Pedal Brief checked it. Climbs without both an official length and average gradient are left out.
