Germany's Carolin Langenhorst and Oskar Kwiatkowski of Poland were loud and clearly delighted first-time Snowboard World Cup winners in the women's and men's parallel giant slalom big finals in the Swiss venue of Scuol.

Langenhorst, 26, got the better of a formidable opponent in the big final in the form of compatriot, contemporary and four-time World Cup overall winner Ramona Theresia Hofmeister.

But the Olympic bronze medallist is still in contention to claim a fourth consecutive overall Crystal Globe, and fifth in total, despite a slow start to the season due to a back injury and is slowly coming into form at the right time.

After today’s result, Hofmeister sits atop the parallel giant slalom standings and is second in the combined category.

Today was Langenhorst’s day, however, and the 26-year-old started as she meant to go on by qualifying in top position.

In the knockout rounds, she beat Switzerland's Larissa Gasser by just 0.11sec to progress to the quarter-finals, where she beat Sabine Schoeffmann of Austria, who skidded out of the course to leave her a clear run to the finish line and the semi-final.

There she faced another home rider, Julie Zogg - the only Swiss in either the men’s or the women’s finals to progress this far - and won by just 0.09.

Zogg made the podium after winning the small final.

Langenhorst was "speechless" after her win.

"I tried to be a bit more chilled and relaxed and just went from run to run and I think that was the key today," she said.

Kwiatkowski's opponent in the big final was Mirko Felicetti of Italy.

En route, he had beaten two leading Austrians Alexander Payer, the leader of the parallel slalom tour, and current overall tour and parallel giant slalom leader Andreas Prommegger, a 22-time World Cup winner from 280 starts.

But the Pole held his nerve in a tight contest that ultimately saw Felicetti, who was aiming for only a second-ever World Cup win himself, come unstuck late on.

Kwiatkowski was able to glide through for the win, claiming a first World Cup victory after 57 starts.

"This is my favourite hill," said a beaming Kwiatkowski post-race, citing "grippy" snow that’s "nice for carving" as reasons for loving Scuol. 

"I’m very happy and very tired."

There was disappointment for the women's tour leader, Daniela Ulbing of Austria, who remains top of the standings despite crashing out in the quarter-finals.

The next World Cup races take place in Bansko, Bulgaria with back-to-back parallel slalom events on January 21 and 22.
