An investigation into allegations of Russian doping found widespread, state-directed doping surrounding the 2014 Sochi Olympics and beyond.
The report, known as the McLaren report after the investigator who led it, concludes that a Moscow lab was the last-resort "failsafe" that would make sure an initial positive test result disappeared if all other steps failed. The strategy that covered up hundreds of positive tests now has a name: The Disappearing Positive Methodology.
___
KEY FINDINGS:
— The Moscow Laboratory operated, for the protection of doped Russian athletes, within a state-dictated failsafe system.
— The Disappearing Positive Methodology was planned and operated over a period from at least late 2011 until August 2015.
