The second fastest female marathon runner ever has been given a two-year doping ban.
Russia's Liliya Shobukhova, who won the 2010 London Marathon, has had all of her results since October 9th 2009 wiped from the record books.
Russian Athletics says abnormalities were found in her biological passport.
On Twitter, world record holder Paula Radcliffe called for money Shobukhova has won to be returned and "rightful winners" to be recognised.
WMMajors: action needs to be taken to show cheating not acceptable. Monies won should be returned and rightful winners recognised.
