Kenyan marathon runner Rita Jeptoo has had her two-year ban doubled after an IAAF appeal was upheld by the Court of Arbitration for Sport. She became Kenya’s first high-profile athlete to fail a test when she tested positive for the performance-enhancing drug EPO in 2014. Jeptoo, 33, says she may have been prescribed banned substances at a local hospital after a road accident. Jeptoo will forfeit her 2014 Boston and Chicago Marathon titles as part of the punishment.
