Athens marathon champion Samuel Kalalei was handed a four-year doping ban for testing positive for banned blood booster Erythropoietin (EPO).
Today, the Athletics Integrity Unit (AIU) announced that Kalalei tested positive at April’s Rotterdam marathon where he finished seventh in a time of 2:10.44.
The 23 year old was provisionally suspended in June.
A number of Kenyan athletes have been banned for doping in recent years, including the 2016 Rio Olympic women’s marathon gold medallist Jemima Sumgong.
In September, Kenya was described as having a “serious problem” with doping by Wada the world anti-doping agency.
