Briefings

Kenyan marathon runner Peres Jepchirchir is provisionally banned by the AIU after testing positive for EPO, a blood booster, in a sample collected prior to her Sydney Marathon victory in August 2026. This incident occurred during a period where the AIU had previously banned athletes for doping, though the specific timeline of the ban's implementation remains unclear. The evidence indicates the violation happened before her win, but the exact date of the ban is not specified.

• Peres Jepchirchir tested positive for EPO, a blood booster, in a sample taken before her Sydney Marathon win in August 2026.
• The AIU has a history of banning athletes for doping, but the specific date when this ban was enforced is not provided in the evidence.
