Kenyan long-distance runner Wilson Kipsang has been banned for four years for violating the doping regulations.
The 38-year-old’s exclusion applies from January 10, 2020, the International Athletic Association’s Independent Anti-Doping Committee (AIU) said on Friday.
Kipsang previously held the world record in the marathon, taking bronze at the 2012 London Olympics.
He has also previously been suspended for violating the doping rules, most recently in January.
Kipsang joins the ranks of Kenyan runners who have been banned. Both Jemima Sumgong, Abraham Kiptum and Daniel Kinyua Wanjiru have suffered the same fate in recent years.
