29-year-old Westberg - who has taken two podium places in team sprint in the World Cup in his career - was poked from the national team this year.
Afterwards, he criticized the union.
On Thursday, he won the men's mass start in roller skiing in Linköping after a sprint battle, 0.3 seconds ahead of Erik Silfver, and in the victory interview afterwards, he called for more participants in the Swedish Championship week.
- I think this is one of the most fun competitions of the whole year.
It is a pity that there are not more people going, that you camp and so on at the same time, it is too bad, says Westberg.
The cross-country skier himself has been a given feature of the Swedish Championship week over the years.
- I have ridden all the years I could.
It's fun, fun competitions, you learn a lot about tactics and positioning and you earn some money, yes, everything possible.
I just see it as positive.
Tomorrow new competitions await, then in sprint.
