Ruti Aga, a top marathon runner, faces a six-year ban from competition. The ban stems from a failed drug test and a fake prescription she submitted. Aga claimed the prescription was for knee pain treatment, but it was found to be fraudulent.

The Ethiopian athlete, who won the Tokyo marathon in 2019, tested positive for methylprednisolone. The Athletics Integrity Unit found the clinic on her prescription did not exist. The signature was from a family member, not a doctor. Aga did not respond to charges, leading to the ban. Read more racing coverage.

The ban includes two years for using the banned substance and four for tampering with the anti-doping process. Aga's career achievements include podium finishes at the Berlin and New York marathons. Related: Ethiopian Marathon Runner Aga Banned for Six Years.
