Nao Kodaira, Miho Takagi and Tatsuya Shinhama all set national records on the first day of the ISU long track World Cup speed skating finals on Saturday.

Kodaira slashed 0.03 second off her own mark when she clocked 36.47 seconds to win the first women's 500-meter race at the Utah Olympic Oval, known for its fast ice due to the high altitude.

"Result aside, I feel like I could've done something more in the 500 meters," said Kodaira, who placed third in the 1,000.
