Russian runner Tatyana Arya-sova has been stripped of her 2011 Tokyo marathon title after testing positive for a banned substance.
The International Association of Athletics Federations finalised a two-year doping ban on Aryasova after she did not challenge its ruling.
The ban is retroactive to April 29 last year and the 32-year-old has been deprived of her Tokyo title as well as all her competition results since the race, the foundation said.
Aryasova tested positive for hydroxyethyl starch (HES) – a masking agent that hides endurance-boosting blood doping – in a sample test after she took the Tokyo prize in 2:27:29 on February 27.
Japan’s Noriko Higuchi, who finished second on the day, was awarded the victory while another Russian, Tatyana Petrova, moved into the runner-up slot in 2:28:56.
