Guo Shuang (郭爽) (born February 26, 1986) is a Chinese professional track cyclist. She won two bronze medals at the 2006 UCI Track Cycling World Championships, in Sprint and Keirin, and two silver medals at the 2007 UCI Track Cycling World Championships, again in Sprint and Keirin.Guo had an eventful semi-final in the sprint at the 2008 Summer Olympics, having won the first heat and conceded the second to her opponent Anna Meares, the third heat saw Guo come down the banking too steeply and her front wheel slipped from beneath her. The heat was re-run and although Guo won by a few millimetres, she was relegated for coming down the tack and pushing Meares onto the côte d'azure on the final lap. This put Meares through to the final ride-off for gold. Guo went on to win the final ride-off for the bronze against Willy Kanis. Wikipedia
