In 1993 Iolanda Chen improved to 14.97 metres, a new outdoor record which would also remain her personal best. Her record was beaten at the World Championships the same year by fellow Russian Anna Biryukova, who jumped 15.09m. In 1995 Chen appeared at the World Indoor Championships and won the gold medal with 15.03 metres, a new world indoor record. This was a huge improvement from the previous championship record of 14.47m. Unfortunately she did not follow up this success, finishing 11th at the World Championships the same year.
