Olympic champion figure skater Kim Yu-na has started training in Moscow for the 2011 World Figure Skating Championships.

During the practice, Kim unveiled her new short program she will perform to music from the ballet “Giselle.”

After she got off the ice, the champion skater said she feels confident and is in good condition. This is Kim’s first return to competition since the 2010 World Championships in March in Torino, Italy 13 months ago.

Kim will skate in the short program event on Friday and in the free skating event on Saturday. This year’s world championships kicks off in Moscow local time.
