The Chinese national team did not even leave the country last season and trained in a bubble under the supervision of Ole Einar Björndalen.
Röiseland finished second in the overall world cup after compatriot Tiril Eckhoff but, like all other skiers, missed out on the planned World Cup competition in Beijing, which would also have served as a pre-Olympics, due to corona restrictions.
The riders have never competed in Beijing and only know that the stadium is high at an altitude of 1700 meters and is known as a cold hole, down to minus 35 degrees, and that there is often a strong wind.
The last windy day in Östersund in the mass start on Sunday was thus a perfect leverage for next year's Olympic season.
- I do not know anything.
I look forward to improving next year.
Is it paddling, couple dancing, is it wind or not, is it sandstorm or blizzard?
Röiseland asks humorously to NRK.
Röiseland took two silvers in Pyeongchang
The most recent Olympics were also in Asia, South Korea's Pyeongchang, and there was important knowledge that the participants gained from the pre-Olympics the year before, 2017.
- It was very important for me to run these competitions.
It changed a lot in terms of weather and was something I learned from.
Then I felt well prepared, says Röiseland, who got two silver medals from the 2018 games.
Normally, the organizer has filmed the course with a go-pro camera so that activists and leaders can get an idea of the conditions, but no such material has been received.
To meet the conditions in Beijing, Norway has planned three high-altitude camps before next season.
The Chinese team is coached by the legendary Ole Einar Björndalen and his wife Darya Domratjeva.
They have not left China for the whole season but have been in a bubble to prepare for next year's championship.
