CALGARY, Alberta -- Sang-Hwa Lee of South Korea set a 500-meter world record Sunday in World Cup speedskating at the Olympic Oval.
Lee's time of 36.80 seconds lowered the mark of 36.94 set by China's Yu Jinh at the world sprint championships on the same oval last Jan. 29.
"I didn't expect the world record here," Lee said through an interpreter. "I was hoping to set it next week in Salt Lake City (at the world sprint championships)."
Other winners were Jens Smeekens of the Netherlands in the men's 500 and Heather Richardson of the United States and Hein Otterspeer of the Netherlands in the 1,000.
World 1,000 record-holder Christine Nesbitt of Canada did not skate Sunday, looking toward Salt Lake City. She won the silver behind Richardson in the 1,000 on Saturday.
Richardson has momentum heading home. She won both 1,000-meter races in Calgary and was second in both 500s, losing to Yu on Saturday and Lee on Sunday.
"I'm excited that it went so well. Hopefully I can do the same thing next weekend," she said.
Richardson was second behind Lee in 37.42. Margot Boer of the Netherlands was third in 37.54.
Richardson's 1,000-meter time was 1 minute, 13.30 seconds. Ireen Wust of the Netherlands was second in 1:13.89, and Brittany Bowe of the U.S. third in 1:13.96.
Smeekens won the men's 500 in 34.39. He was followed by Japan's Joji Kato in 34.44 and Michel Mulders of the Netherlands in 34.55.
Otterspeer's time in the 1,000 was 1:07.76. Shani Davis of the U.S. was next in 1:07.83, and Samuel Schwarz of Germany was third in 1:07.85.
