World champions Norway remained unbeaten this season in cross-country skiing World Cup relay races, with the women untouchable while the men survived a late Russian scare on Sunday.
Ingvild Flugstad Oestberg, Heidi Weng, Therese Johaug and Astrid Uhrenholdt Jacobsen clocked 50 minutes 17.2 seconds in the 4x5-kilometre women's race relay, ahead of the United States and Finland.
The US quartet trailed by 42.1 seconds and Finland were third, 55.9 seconds behind.
Norway's women have won all three relay races contested so far this season, and so have their men after Sjur Roethe, Martin Johnsrud Sundby, Mathias Rundgren and Finn Hagen Krogh topped the 4x7.5km podium in 1:08:29.0 hours.
Russia's Sergey Ustiugov started 30 seconds behind Krogh into the anchor leg, cut the deficit to 12.8 seconds after 5km but was unable to achieve a comeback victory as the Norwegians prevailed by 6 seconds.
Third-placed Italy trailed by 54.3 seconds, pipping a second Norwegian team and Germany by three tenth to complete the podium.
Other Nordic skiing events later Sunday were Nordic combined and ski-jumping large hill competitions in Chaux-Neuve, France and Zakopane, Poland respectively.
