Canada's Tessa Virtue and Scott Moir have the lead in ice dance following the short dance at Gangneung Ice Arena on Monday afternoon.
The defending world champions skated to a Latin musical selection and set a world record with a score of 83.67 points.
Virtue and Moir were the gold medalists in ice dance at the 2010 Vancouver Olympics and silver medalists in Sochi four years ago. They received high grades of execution on all of their elements and are well-positioned for a shot at a second gold.
