Alberto Salazar, a coach of some of the world’s top distance runners, has been barred for four years from the sport for doping violations, the United States Anti-Doping Agency announced Monday night.
The ban resulted from violations including trafficking in testosterone, tampering with the doping control process and administering improper infusions of L-carnitine a naturally occurring substance that converts fat into energy, Usada said.
As head coach of the Nike Oregon Project, Salazar, 61, has trained such stars as Mo Farah of Britain, a four-time Olympic champion on the track; Galen Rupp, the top American marathon runner; and Sifan Hassan of the Netherlands, who set a world record in the women’s mile in July.
