- US athletes, including Korean-American teen halfpipe star Chloe Kim, are already looking forward to the 2018 Pyeongchang Winter Olympics a year before they begin. "I'm really excited to get that Olympic spirit going again," said Mikaela Shiffrin, who won 2014 Olympic slalom ski gold at age 18. "So much has happened between Sochi and now, I feel like I was a baby back then." About 245 US athletes will visit Pyeongchang, where competition opens February 8, a day before the opening ceremony. In all, 2,800 athletes from 95 nations will compete in 102 medal events over 15 disciplines. Among expected US stars will be 16-year-old snowboarder Kim, who will talk with Seoul college students Wednesday about overcoming challenges and work Friday in Pyeongchang with youth snowboarders from her parents' home country.
