Reigning marathon world champion Peres Jepchirchir has been suspended by the Athletics Integrity Unit (AIU) after testing positive for EPO.

The Kenyan returned an adverse analytical finding for the performance-enhancing drug in a sample taken before her recent victory at the Sydney Marathon.

She is a four-time World Marathon Major winner, a former world record holder in the half-marathon and claimed Olympic gold in the marathon at Tokyo 2020.
