Indian athlete Gomathi Marimuthu has challenged the four-year ban handed to her for failing a dope test, at the Court of Arbitration for Sport.

Gomathi’s gold medal at the 2019 Doha Asian championship in the 800m event had been taken away and she was banned for four years by the Athletics Integrity Unit after her ‘B’ sample also returned positive for anabolic steroid nandrolone.

“An appeal has been filed with CAS as per procedures. We have appealed against the four-year ban and the fine of 1,000 British Pounds imposed on me,” she told PTI.

The Tamil Nadu athlete had tested positive for the anabolic steroid nandrolone at the 2019 Asian track championships in Qatar in April.

All of Gomathi’s competition results between March 18 and May 17, 2019 stand annulled. Her medals, titles, ranking points and prize and appearance money are to be forfeited as well.

The 31-year old will be banned till May 2023.

Gomathi, who was provisionally suspended in May last year when her ‘A’ sample returned positive, was also ordered to pay the AIU, within 28 days, 1,000 British pounds towards legal and other expenses.
