Speed skater Lee Sang-hwa clocked 1 minute and 14.39 seconds to set a new Korean record in the women's 1000-m race at the ISU World Sprint Championships in Kearns, Utah, on Sunday.

She finished 12th while Canada's Christine Nesbitt won with a time of 1:12.91. Lee beat her own Korean record of 1:15.26 set in the same venue in December 2009. It is the first time a Korean female skater has beaten 1 minute and 15 seconds.
