The Olympic and world champion marathon runner has been suspended due to doping.

Peres Jepchirchir, the Olympic marathon champion, has been temporarily suspended by the Athletics Integrity Unit due to doping allegations. A blood sample taken before the Sydney Marathon tested positive for EPO. The investigation is ongoing. Jepchirchir has previously won major marathons in New York, Boston, and London. Over the past decade, the AIU has suspended more than 140 Kenyan athletes for doping violations. WADA's president urged Kenya to lead in anti-doping efforts, especially after being awarded the 2029 World Athletics Championships.
