Winnie Jemutai Boinett has been suspended by the Athletics Integrity Unit (AIU) for three years as she tested positive for testosterone.

Boinett’s sample that she provided in competition at the XLI Cross Internacional de Italica in Seville, Spain, on November 12, 2023, had the presence of testosterone. Testosterone is banned under the World Anti-Doping Agency’s (WADA) prohibited list.

The 20-year-old 5000-metre runner admitted to the violation and accepted the consequences, including the forfeiture of any medals, titles, points, prize money, and other prizes won since the date of the provisional suspension. Therefore she had a reduced sentence from four years to three years.

The World Anti-Doping Agency (WADA) and the Anti-Doping Agency of Kenya (ADAK) may appeal the decision to the Court of Arbitration for Sport in Lausanne, Switzerland.

The World U20 bronze medallist in the 1500m may have also age-doped as Wikipedia lists her birthday as 4 October 4, 2003, June 4, 2003, or February 9, 2002. She has run the 5000m as fast as 14:39.05.
