Russia’s track and field federation says veteran marathon runner Albina Mayorova has been banned for four years for doping.
The All-Russia Athletics Federation said Monday that the suspension was handed down by the Court of Arbitration for Sport (CAS) after the two-time Olympian tested positive for excess testosterone in a test taken last year.
The ban is likely to spell the end of the 39-year-old Mayorova’s competitive career.
Mayorova’s best result at a major championship was 8th at the 2012 Olympics in London. She has also been a top-10 finisher at the London, Boston and Chicago marathons.
