US ski star Lindsey Vonn made a successful return to training as she battles to overcome a recent injury to recover in time for the 2014 Winter Olympics. Vonn said on Twitter that she put in some super-G training in Vail on Friday, as her alpine World Cup rivals tackled the first downhill of the season at Beaver Creek. "Trained SG today in Vail and felt great," Vonn tweeted. "Taking it step by step and so far so good!" Vonn, the reigning Olympic downhill champion, had been slated to race in Beaver Creek this week for the first time since surgery in February to repair her right knee, which she injured in a frightening fall at the World Championships in Austria. But Vonn suffered a partial tear of one of her surgically-repaired ligaments in a training run 10 days ago. She skied again for the first time on Thursday, and has said she could compete at next week's World Cup stop at Lake Louise, Canada. Vonn said in a television interview this week that she was confident she would be able to ski in February at the Sochi Winter Olympics. Vonn, the girlfriend of 14-time major golf champion Tiger Woods, won World Cup overall titles in 2008, 2009, 2010 and 2012 and with 59 race wins she is three shy of matching the women's World Cup record owned by Austrian Annemarie Moser-Proell.
