Born in Tulcea, Romania, Elena Fidatov-Moruzov made her international debut at the 1984 IAAF World Cross Country Championships, reaching the top 40 in the women's long race. She was much improved at the 1985 World Cross Country event and her tenth-place finish helped the Romanian women, led by Fiţa Lovin, to the team bronze medal. She was third at the Balkan Cross Country Championships that year and succeeded her compatriot Mariana Chirila to the title the following season. Fidatov came ninth in the long race at the 1986 IAAF World Cross Country Championships. She did not compete internationally in the late 1980s.
