Chinese cycling Olympic hopeful Guo Shuang has shrugged off the world championship's dismay and expressed her confidence for the upcoming Beijing Olympics after a two-month training in Switzerland on Sunday.

"I am still a little bit tired, but in a good spirit. Training in the UCI center gave me more confidence for the Olympics," said Guo, who is still fighting against jet leg after coming home on Saturday night.

Born in Inner Mongolia, Guo started cycling at the age of 13, and established her status by beating veteran Jiang Yonghua, the Athens silver medalist to win the crown in the 2005 Chinese National Games.

She then became Chinese cycling's Olympic gold hopeful after collecting one gold medal in sprint at the Asian Games in 2006, two bronze medals in sprint and keirin at the World Championships in 2006, and two silver medals in sprint and keirin at the World Championships in 2007.

However, the 22-year-old star suffered a heavy blow in the Manchester world track championship in March, where she was placed fourth in sprint.

"I was just too eager to win, and did not follow the coach's strategy well. There are many good sprinters in world cycling, I still need to learn more from my opponents," explained Guo.
