Sochi 2014 Olympic champion Marielle Thompson secured her second consecutive victory on the International Ski Federation Ski Cross World Cup circuit at the night event in Arosa, Switzerland.

Thompson, winner of the women's race in Montafon in Austria on Saturday (December 14), triumphed in the big final to continue her bright start to the season.

The Canadian crossed the line ahead of Switzerland's Olympic bronze medallist Fanny Smith, the defending overall champion.

Smith did enough for second place, while Sandra Näslund of Sweden took third and her compatriot Alexandra Edebo finished outside of the podium places in fourth.

Canada also enjoyed success in the men's event, won by World Championships bronze medallist Kevin Drury.

The 31-year-old surged clear of the rest of the field in the big final to record his second victory of the season.

Viktor Andersson of Sweden was second and Alex Fiva of Switzerland did enough for third.

Adam Kappacher of Austria was fourth.

The Ski Cross World Cup season resumes in Innichen in Italy on Friday (December 20).

Two men's and women's races are on the schedule for the event in the Italian resort, concluding on Sunday (December 22).
