Related: Eight Athletes Caught Doping ahead of China's National Games
China's Anti-doping Agency (CHINADA) Tuesday announced a top women's marathon runner had become the first Chinese athlete failing the biological passport program.
Former Beijing Marathon winner and national champion Wang Jiali has been suspended since February after anomalies were discovered in her biological passport, which recorded data from her blood samples collected between May 2012 and January 2013.
The 27-year-old has never tested positive in anti-doping tests before.
China introduced the new anti-doping scheme in 2012.
