The Athletics Integrity Unit (AIU) handed a provisional ban for doping to Wilson Kipsang (former world marathon record holder).
The 37-year-old Kenyan was suspended for “whereabouts failures and tempering”, both violations of World Athletics anti-doping rules.
Kipsang claimed the world record clocking 2hr 3min 23sec in the 2013 Berlin Marathon.
It’s not the first time that he has fallen under the doping radar. In September 2014 he escaped punishment when he missed an out-of-competition drug test.
If proven, he risks a two-year ban for his latest infringement. This development was the latest blow for Kenyan athletics ahead of the 2020 Tokyo Olympics as he joins the growing list of Kenyan Athletes who have been suspended for doping offences.
