A circuit accessible to all runners, but not to be taken lightly! Once out of Novalaise, the route quickly picks up speed towards Monthieux, alternating between small roads and pleasant paths. The next section allows to test yourself with a nice downhill before Gerbaix. Once you've passed the village, you've done the hard part, although you'll have to negotiate a final climb to the Mairie de Marcieux, before unwinding back to the starting point. A pleasant loop to discover the north of the territory of the lake.
