Andreassen's young age came into play when the Norwegian Skiing Association made its selection.
Andreassen came fifth in the sprint at the Norwegian senior championships and took three golds and a silver at the JVM and has sportily qualified for a start.
She is seen as the future of Norwegian skiing.
- Milla has been superior all year, and should be matched against the best in the world.
The race is only half an hour away from where she lives and would be a motivational boost for her heading into the summer and the years to come, says Johaug.
Last weekend there was a selection competition for the Drammen sprint in classic style.
Andreassen, born in 2005, was not allowed to participate in the competition, which was only open to riders born in 2003 and 2004.
"Jakob Ingebrigtsen won EC gold as a 17-year-old"
- It is defensive.
The ski association should use more common sense.
Yes, she is young, but hey!
Jakob Ingebrigtsen won EC gold as a 17-year-old, Martin Ödegaard went to Real Madrid at a young age.
It has gone well for them, points out NRK's expert Johaug.
The Norwegian federation was criticized when the three-time world champion in Planica, Simen Hegstad Krüger, was not allowed to ride the final five miles even though he wanted to and a reserve was brought in.
Hans Christer Holund also got the nob.
In Sweden, they have gone in the other direction.
Alvar Myhlback received a dispensation to run the Vasaloppet over 90 km as a 16-year-old.
He thanked for the trust and went into a sensational eighth place.
