Career
Nelidina competed for Russia until 1998, when she briefly switched to competing for Azerbaijan. She switched back to skating for Russia the following year. Her highest placement at a senior-level International Skating Union Championship was 13th at the 2003 World Championships.
During her career, she was coached by Tatiana Pomerantseva, Zhanna Gromova, and Viktor Kudriavtsev.
Nelidina landed a triple axel in competition at the 2002 Skate America. Together with Yukari Nakano, who also completed a triple axel at that competition, Nelidina was the first female skater in 10 years to perform a triple axel in international competition.
She is the first European lady skater to land a triple axel in competition, the other skaters having been from Japan and the United States. After retiring from competition, Nelidina began coaching in Moscow.
