Paris: Kenyan marathon runner Samuel Kalalei was handed a four-year doping ban on Wednesday after testing positive for banned blood booster EPO, the Athletics Integrity Unit (AIU) announced as the African powerhouse suffered another body blow.
Kalalei, 23, tested positive at April's Rotterdam marathon where he finished seventh in a time of 2h 10min 44sec, a personal best.

In September, Kenya was described as having a "serious problem" with doping by WADA the world anti-doping agency.
