- I know many people think I'm unbeatable, but I know myself that I am not. I said that in the World Cup (this spring), and we got to prove that ten kilometers (classic) then. Suddenly it turns around, says the 31-year-old.

Johaug won that race in Austrian Seefeld, with 12.2 seconds ahead of Swedish star shot Frida Karlsson.

- Yes, but it was pretty even, says the Norwegian.

In the afternoon ten kilometers in free style in Italian Toblach, the third stage of seven in the Tour de Ski, Johaug is a big favorite.
