She flagged for it already yesterday after the mass start.

- I was so tired today, that is.

It was like a struggle from the start, so it was not like I went and smiled the whole race.

I would not say that, she said and already after Friday's individual race she was dumb and did not get her capacity.

One theory is she is trained and needs rest.

SVT Sports expert Johanna Ojala was a little worried when she saw Karlsson's interview.

- It really needs to be investigated what it is, and adjustments and adjustments made, she says.

Karlsson made a comeback in Falun after the notable damage to the hotel room during the Tour de Ski which she was forced to break.

Sofia Henriksson took Karlsson's place.

Calle Halfvarsson also gave up the sprint.
