Motonaga Arito triumphed in the men's 1,500 metres, while Dutch athlete Myrthe de Boer took gold in the women's event at the St Moritz Speed Skating Oval.

Japan have won both men's races at the Games so far, a record matched by the Dutch team in the women's events.

Arito topped the podium having completed the three-and-three-quarter laps of the course on the frozen lake in a time of 1min 52.54sec.

The 17-year-old Japanese was 1.5 seconds faster than nearest challenger Pavel Taran of Russia, who took silver in 1:53.74.

American Jonathan Tobon earned bronze in 1:55.67.

"I was aiming for the gold medal today," said Arito. 

"I’m really happy to have been able to achieve my goal. 

"I feel proud about my race."

The women's race was a much closer affair as De Boer edged out silver medallist Yuka Takahashi of Japan by 0.14sec.

De Boer, seventh in yesterday's 500m, clocked 2:10.44 to seal her country's second speed skating title at Lausanne 2020.

Takahashi was forced to settle for silver in 2:10.58, while Yang Binyu of China claimed bronze in 2:10.93.

"I just went from the lowest of lows to the highest of highs," De Boer said. 

"After yesterday’s result in the 500m I was really disappointed, but it proved to be a huge learning opportunity for me.

"During the final lap, my muscles were cramping a lot because of competing at a high altitude and the windy conditions. 

"It felt like I was racing incredibly slow at some point, but having won gold I do not care about my time anymore."
