The Russian race walker Yelena Lashmanova has been banned for doping offences and will retrospectively lose her Olympic gold from 2012 and world championship win from a year later, the Athletics Integrity Unit (AIU) said Monday.
"Following AIU charges ... Lashmanova has been banned for two years, starting 09 March 2021, for the use of prohibited substances," a statement said.
The AIU added the 29-year-old would have her results from February 18, 2012, to January 3, 2014, annulled.
Lashmanova set a then world record in winning the 20-kilometre walk at the 2012 Games in London.
The AIU said the decision could still be appealed.
