155 km, 4464 m of elevation gain, three climbs via three different roads: that’s the “Fous de Chamrousse” challenge. Chamrousse has three main roads to the summit, with elevation and distance eerily similar to the famous Cinglés du Ventoux challenge. And since it’s right next to Grenoble, you can ride straight from the city.
