Persistent injury problems has forced world 400m hurdles record holder Yuliya Nosova-Pechonkina of Russia to announced her retirement from the track.
Nosova-Pechonkina, who set the world record of 52.34seconds in 2003, has not been able to run consistent since finishing second at the World Championships in Osaka 2007.
The Russian made a brief comeback this season, but after running a modest 54.86secs at the Russian Championships she once again struggled to get recover from a nagging injury.
She now decides to become a bank officer.
The 2005 world champion from Helsinki, said it was a difficult decision to retire, but felt a come back would have been extremely tough on her, both mentally and physically, especially with her older injuries constantly lurking.
Nosova-Pechonkina will now sit and watch to see if Jamaican Olympic and world champion Melaine Walker will successfully break her world record.
The Jamaican came close to the mark at the world championships in Berlin last month, running a sizzling 52.42secs to win the title.
American Lashinda Demus will also have a say in the world record quest.
