1984 proved to be the only year where Ponomaryova would be the world's number one 400 m hurdler, however her international career would continue for another decade. In 1985, now competing as Margarita Khromova, she finished sixth in the World Cup in Canberra. In 1986, she reached the European Championship final in Stuttgart, placing eighth. The following year she was a semi-finalist at the World Championships in Rome, narrowly missing the final.
