Fifth Olympic runner disqualified from ‘dirtiest race in history’ – 12 years after London Games

Tomashova was banned for 10 years by the Court of Arbitration for Sport (CAS) in September for anti-doping rule violations at the Games and stripped of her silver medal from the race, often described as the “dirtiest” in history.

She became the fifth of the 13 athletes in the final to receive a retroactive sanction for an anti-doping rule violation, the AIU said in a statement.

Tomashova, now 49, finished fourth in the race and was awarded silver after the first two finishers were later banned.

CAS banned Tomashova on September 3 and ordered that the Russian’s results from June 2012 to January 2015 be annulled.

“We are committed to protecting the integrity of athletics and, even when events have long passed, we will investigate potential violations fully,” AIU chair David Howman said in a statement.
