Jonna Sundling took the World Championship's first gold, in sprint. She is also selected to run Sunday's skiathlon, just like Emma Ribom who also ran the sprint.
They flank the distance skiers Frida Karlsson, Ebba Andersson and Moa Ilar.
Sweden gets to have five skiers since Ebba Andersson is the reigning champion.
The men run the skiathlon (10 km classical style + 10 km free style) on Saturday and Sweden will be represented by William Poromaa, Jens Burman, Calle Halfvarsson and Edvin Anger.
