Ruti Aga
Introduction
Ruti Aga is a 32-year-old Ethiopian marathon runner who won the 2019 Tokyo Marathon in 2:20:40 and finished on the podium at World Marathon Major races in Berlin and New York, placing second at majors three times. On October 22, 2026, the Athletics Integrity Unit banned her for six years after she tested positive for a prohibited substance and then tried to explain the result with a prescription from a clinic that did not exist, signed by a “doctor” who turned out to be a family member with no medical registration. The Guardian described her as one of the world’s leading marathon runners at the time of the ban.
Background Information
Aga’s positive sample came from the Meishan Renshou Half Marathon in China on March 15, 2026, a race she won; the laboratory found methylprednisolone, a glucocorticoid corticosteroid classified as a Class S9 substance on the World Anti-Doping Agency Prohibited List and prohibited in-competition, which WADA classes as performance-enhancing. She attributed the finding to treatment for a knee injury, claiming a doctor in Ethiopia had administered the substance. The AIU opened an investigation after the result and interviewed her about the treatment claim.
The Controversy or Incident That Led to Their Cancellation
Banned six years for doping and tampering with the investigation. The AIU found Aga committed anti-doping rule violations for the presence and use of methylprednisolone and for tampering, imposing two and four years respectively β six years in total running from her provisional suspension.
The AIU said Aga submitted a prescription purportedly from a clinic that did not exist, issued by a “doctor” who turned out to be a family member with no medical registration with the relevant authority. “When questioned, the family member claimed to have used an old prescription pad from a former workplace,” the unit said. “But that clinic confirmed the individual had never worked there and the prescription was not theirs.” The investigation concluded she had provided false information in an AIU interview and produced a forged or manipulated document purporting to verify the prescription. According to the Guardian, Aga then failed to respond to the charges for the use of methylprednisolone and tampering, meaning the six-year ban was issued without a hearing. The sanction comprises two years for the presence and use of a specified substance and four further years for tampering or attempted tampering with any part of doping control.
Public Reaction and Consequences
The ban, announced on a Thursday by the AIU, removes one of Ethiopia’s most decorated marathoners from the sport through 2032. Aga had been provisionally suspended since September 10, 2026, and the six-year ban runs from that date, extending to September 2032. Her results from the March 2026 race β where she won the half marathon while positive β fall within the disqualified period that accompanies the finding. No public statement from Aga was reported in either source’s coverage.
Current Status
Aga is serving a six-year ban from all sanctioned athletics competition that began with her provisional suspension on September 10, 2026. The case was resolved by the AIU without a hearing after she failed to respond to the charges, per the Guardian’s report of the unit’s announcement. Neither source reports any appeal lodged against the decision.
Impact on Their Career/Life
The ban ends competitive eligibility for the remainder of what would have been her prime marathon years and strips the credibility of her 2019 Tokyo Marathon triumph’s standing record, with the AIU framing the sanction as punishment for both doping and an attempted cover-up. The Guardian noted the fake-prescription finding β a nonexistent clinic and an unregistered family member signing as a doctor β as the aggravating element that pushed the sanction beyond the standard penalty for her substance. Her podium finishes at Berlin, New York and other majors are now bookended by a doping disqualification that removes her from the elite field entirely.
