Two more Kenyan marathon runners have been handed provisional suspensions for testing positive for banned performance-enhancing drugs.

Michael Kunyuga tested positive for norandrosterone. Maiyo Johnstone Kibet tested positive for erythropoietin (EPO).

Norandrosterone is a metabolite of nandrolone, a very popular anabolic-androgenic steroid.

EPO is a red blood cell booster.

Kunyuga has run the marathon as fast as 2:06:43 in Seville, Spain in 2020. In May this year, the 35-year-old ran the Riga Marathon in the time of 2:12:44.

It has been a long time since Kibet ran at his, however, in 2011 he ran a 2:10:02 time in Frankfurt, Germany.
His best this year is 2:17:44 in Kigali, Rawanda.

The Athletics Integrity Unit (AIU) reported the suspensions which are appealable.

Kenya has the most suspended athletes in the world outside of Russia, which has a blanket ban.

Navjeet Kaur Dhillon was handed a doping suspension as reported by the AIU on Aug 26. She failed an out-of-competition doping test that was conducted by the AIU in Almaty, Kazakhstan, on June 24. She tested positive for a metabolite of the anabolic steroid Dehydrochloromethyltestosterone, a non-specified substance prohibited by WADA at all times.

Her suspension is also open to apeal.

Dhillon earned a bronze medal at the 2018 Commonwealth Games. Her personal best is 59.18m. She is a three-time national champion, twice in the discus, once in the shot put.
