American Shani Davis, who is from Chicago, won the men's 1,000 a day after taking the 1,500.
The two-time Olympic champion finished in 1:06.02 in the 1,000.
"I know I don't have a lot of my speed yet, but doing a 24.6 lap is really good considering my condition," Davis said. "I just look to improve from this race."
The Netherlands' Kjeld Nuis followed in 1:07.02, and American Brian Hansen was third in 1:07.03.
Davis won in front of his family and friends.
