3-time Chicago Marathon winner Shobukhova gets 2-year ban for doping, stripped of victories

MOSCOW - Three-time Chicago Marathon winner Lilya Shobukhova has been banned for two years for blood doping.

The Russian athletics federation says it banned Shobukhova until next January and stripped her results from Oct. 9, 2009, for abnormal biological passport values.

Shobukhova won three times in Chicago and once in London in that time, also collecting $1 million prize money as a two-time leader of the World Marathon Majors rankings.

Race organizers say "any athlete found guilty of a doping offence will be required to repay any prize or appearance money earned at WMM events including WMM series prize money."

The 36-year-old Shobukhova is the second-fastest women's marathon runner behind record holder Paula Radcliffe of Britain.

Radcliffe wrote on Twitter that "Lilya Shobukhova finally exposed as a drug cheat."

Shobukhova can appeal.
