Hours after Eldar Roenning, Martin Johnsrud Sundby, Sjur Roethe and Didrik Toenseth claimed the second of two men's 4x7.5km relays this season, the women did the same in France.
The quartet of Heidi Weng, Therese Johaug, Kristin Stoermer Steira and the returning Marit Bjoergen romped to a comfortable victory to add to Norway's win at the season opener in Gaellivare.
Norway also took victory in the team sprint classic in Liberec last weekend and in the only race in which they haven't won, the team sprint freestyle in Quebec at the start of December, they were third.
The Norwegian women's quartet beat off the charge of Finland by 27.9seconds with the second-string four of Vibeke Skofterud, Ingvild Flugstad Oestberg, Martine Ek Hagen and Astrid Uhrenholdt Jacobsen third.
And it was thanks to Bjoergen, who returned for the first time since suffering an irregular heartbeat to win the 10km classic mass start in La Clusaz, who powered Norway to victory on the final leg.
Third through Weng to start, then into first thanks to Johaug, Bjoergen recovered from starting in second place after Steira's third leg to overhaul Finland and build a near 30-second advantage.
