This first day of competition, there are several Swedish medal jumps among the starters.
On the men's side, we have David Mobärg, Viktor Andersson, Erik Mobärg and Fredrik Nilsson.
On the women's side, it was long unclear whether the Swedish star Sandra Näslund would start in the World Cup due to injury problems.
The same was true of Alexandra Edebo.
But they are both involved and represent Sweden on the women's side this world championship.
The competitions are commented on by Björn Becksmo together with expert commentator, Lars Lewén.
