Departing from the Maison du Lac, you'll follow the eastern shore of Lac d'Aiguebelette. After a warm-up along the emerald waters, you'll reach the foothills of the Chartreuse massif. Passing the côte de Dullin, you'll reach the heights of the western shore, and Novalaise. It's the ideal place for a coffee-stop, so don't forget to recharge your batteries before the Col de la Crusille and the Côte de Marcieux! Once you've reached the top, just let yourself roll all the way to the finish.
Good plans : For a less steep finish, you can go directly to the village of Marcieux via the "Route de Marcieux". This variant offers a total distance of 47.5 km and 1,000 metres of ascent.

Admission fee : Free access.

Opening : All year round daily.
