Ingvild Flugstad Östberg had an injured spring.
She first suffered an overload injury in March.
Then she was back in training with the Norwegian national team in June.
But then she was injured again, with a fracture in one foot.
According to NRK, it is not entirely known what is the direct reason why she is over this year's season, but it is likely that the injury problems have contributed to the decision.
"" Unfortunately I will not ski this season, which of course is sad. That's what I work hard for every day and what I love to do. As I said, there is no doubt that I will do my best to come back strong, she writes in an email to Norwegian TV2.
