The duo did not really get the start they had hoped for at this Olympics as there were two worse places in the initial Olympic competitions in mixed relay and distance running.

But now the sisters have studied Friday's sprint track, 7.5 km, in detail to find the key to success.

- It has been our absolute greatest strength all season, that we really go through the tracks and set up a clear plan for how we want to go, Hanna Öberg tells Sportbladet and explains that it is also about how she should dispose of the power during the race.

"Incredibly tagged"

Hanna also presses that she will go "full blown".

- Now there is almost nothing to worry about, but now it's just driving.

Elvira, just like the big sister, is looking forward to Friday's race.

- I am incredibly tagged and feel that I have a good plan for how to approach the race.
