Kenyan-born Bahraini Eunice Jepkirui Kirwa, who won marathon silver at the Rio Olympics in 2016, has been suspended for four years for doping, the Athletics Integrity Unit (AIU) announced Monday.
Kirwa had been provisionally banned since May after the prohibited blood-booster EPO was detected in her blood sample. Her four-year suspension is backdated to May 7, 2019.
