Russian marathon runner Mayorova banned for doping

MOSCOW (AP) 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 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 eighth at the 2012 Olympics in London. She has also been a top-10 finisher at the London, Boston and Chicago marathons.
