BEIJING, Feb. 10 (Xinhua) -- Swiss freestyle skier Mathilde Gremaud successfully defended her title in the women's slopestyle on Monday at the Milan-Cortina Winter Olympics.

Gremaud delivered under pressure after China's Gu Ailing led with 86.58 points in the opening run. The Swiss responded with a strong second run, scoring 86.96 points to edge Gu by 0.38 points and secure the gold medal.

Falling short again to Gremaud after Beijing 2022, Gu said, "I think it's kind of funny that both Olympics we were within half a point of one another. If anything, I think it's just testament to the growth of women's free skiing. It's so special to be a part of that."

In speed skating, Leerdam set a new Olympic record of 1:12.31 to win the women's 1,000m, 0.28 seconds ahead of her compatriot Femke Kok, while Beijing 2022 champion Miho Takagi of Japan claimed bronze in 1:13.95, her eighth medal across five Games. China's Yin Qi and Han Mei placed 12th and 13th respectively among the 30 participants.

Switzerland added another gold in alpine skiing as Franjo von Allmen and Tanguy Nef mounted a comeback to win the men's team combined event, which made its debut on Olympic program. It also marked Von Allmen's second gold at Milan-Cortina, after he claimed the Games' opening gold in Saturday's downhill race.

Germany's Philipp Raimund captured gold in the men's normal hill ski jumping event with 274.1 points.

Japan's Kokomo Murase claimed gold in the women's snowboard big air with 179.00 points. China's Zhang Xiaonan finished fifth in her Olympic debut, matching the country's best result in the event.
