Col de la Porte

This ride will take us into the heart of the Parc Naturel Régional du Massif de Chartreuse. A lush green reserve with imposing limestone cliffs that lends its name and colour to the green liqueur. The route tackles the Col de la Porte which featured on stage 16 of the 2020 TDF.

Starting in Le Touvet, on the edge of Parc the route heads up and over the Col de Marcieu to La Terrasse. From here, it's up again on a spectacular, but challenging, balcony road. 

We then pass through Brevardiare and push on, up the Col de la Porte, crossing the top at 1326m under the shadow of Chamecaude. From here we continue to follow in the path of the 2020 tour, dropping sharply down to Meylan, where we finish the ride.
