Japan’s Miho Takagi and Tatsuya Shinhama clinched gold at the World Sprint and World Allround Speed Skating Championships at Hamar.
Victories in yesterday's 500 metres and 1,000m races saw Takagi lead the way in the women's competition at the Vikingskipet venue.
She sought to preserve her lead on the second day of action.
Takagi began strongly with a second place finish in the 500m event in a time of 37.52, just 0.06 seconds slower than her compatriot and Olympic champion Nao Kodaira.
Victory was sealed by Takagi when she triumphed in the 1,000m race in 1:13.93.
The Netherlands' Jutta Leerdam and United States' Brittany Bowe completed the top three in times of 0.54 and 0.63 seconds back.
Takagi finished the competition with an overall total of 148.870 points across the four races.
Kodaira was left settling for silver on 150.150, with Russia's Olga Fatkulina winning bronze on 150.430.
Takagi becomes the first female skater to win the world sprint and all-round title, which she won in 2018, since Anni Friesinger-Postma achieved the feat in 2007.
A Japanese double was achieved when Shinhama triumphed in the men's competition.
Having won the 1,000m competition yesterday, Shinhama was victorious over the shorter 500m distance today in a time of 34.39 seconds.
Canada’s Laurent Dubreuil continued to pressurise the Japanese skater, after he placed second in 34.56.
