Long distance runners Ibrahim Mukunga Wachira and Keneth Kiprop Renju have become the latest Kenyans to be provisionally suspended by the Athletics Integrity Unit (AIU) for doping.

Wachira was sanctioned for the presence or use of norandrosterone while Renju was charged for the presence or use of methasterone.

Both substances are banned under the World Anti-Doping Agency 2022 prohibited list and are filed under the anabolic androgenic steroids category.

They join a list of Kenyan long-distance runners to be either provisionally suspended or outright banned recently.

Boston Marathon winner Diana Kipyokei tested positive for triamcinolone and has also been charged with tampering for allegedly "obstructing or delaying the AIU's investigation through the provision of false information or documentation”.

She won the women's race in America on October 11 last year but failed a test immediately after.

Meanwhile, Philemon Kacheran Lokedi has been banned for three years after testing positive for testoerone and its metabolites "with exogenous origin".

Felix Kipchumba Korir – the winners of the 2018 Nanjing Marathon - and Emmanuel Saina have also both received three-year bans after testing positive for norandrosterone.
