Russian runner Tatiana Aryasova has been stripped of her 2011 Tokyo Marathon title after testing positive for a banned substance.

Aryasova tested positive for hydroxyethyl starch (HES) in a urine sample taken after she won the Tokyo race in 2hr 27min and 29sec on February 27.

The Tokyo Marathon Foundation stripped Aryasova of her title after she failed to challenge a two-year doping by the International Association of Athletics Federation during an appeal period which ended last week.

Japan’s Noriko Higuchi, who finished second, was awarded the victory with a time of 2:28.49. Russia’s Tatyana Petrova moved into the runner-up position after finishing with a time of 2:28.56.
