McLaren Report

Last updated

The McLaren Report (Russian : Доклад Макларена) is the name given to an independent report released in two parts by professor Richard McLaren into allegations and evidence of state-sponsored doping in Russia. It was commissioned by the World Anti-Doping Agency (WADA) in May 2016. In July 2016, McLaren presented Part 1 of the report, indicating systematic state-sponsored subversion of the drug testing processes by the government of Russia during and subsequent to the 2014 Winter Olympics in Sochi, Russia. [1] In December 2016, he published the second part of the report on doping in Russia. [2] [3]


July 2016 report (part 1)

On 18 July 2016, Richard McLaren, a Canadian attorney retained by WADA to investigate Grigory Rodchenkov's allegations, published a 97-page report covering significant state-sponsored doping in Russia. [4] Although limited by a 57-day time frame, the investigation found corroborating evidence after conducting witness interviews, reviewing thousands of documents, cyber analysis of hard drives, forensic analysis of urine sample collection bottles, and laboratory analysis of individual athlete samples, with "more evidence becoming available by the day." [4]

The report concluded that it was shown "beyond a reasonable doubt" that Russia's Ministry of Sport, the Centre of Sports Preparation of the National Teams of Russia, the Federal Security Service (FSB), and the WADA-accredited laboratory in Moscow had "operated for the protection of doped Russian athletes" within a "state-directed failsafe system" using "the disappearing positive [test] methodology." [4] [5] [6] [7] McLaren stated that urine samples were opened in Sochi in order to swap them "without any evidence to the untrained eye". [4]

At the Olympics, urine samples are stored in security bottles named the "BEREG-KIT", which must be broken open after being closed; the investigation, however, found that using a specific tool, the bottles were possible to open, and found scratch marks on the inside normally invisible to the naked eye. [8] The official producer of BEREG-KIT security bottles used for anti-doping tests, Berlinger Group, stated, "We have no knowledge of the specifications, the methods or the procedures involved in the tests and experiments conducted by the McLaren Commission." [9]

According to the McLaren report, the Disappearing Positive Methodology (DPM) operated from "at least late 2011 to August 2015." [4] It was used on 643 positive samples, a number that the authors consider "only a minimum" due to limited access to Russian records. [4]

Part 1 of the Report is available publicly on WADA's website:

December 2016 report (part 2)

On 9 December 2016, McLaren published the second part of his independent report. The investigation found that from 2011 to 2015, more than 1,000 Russian competitors in various sports (including summer, winter, and Paralympic sports) benefited from the cover-up. [2] [3] [10] [11] Emails indicate that they included five blind powerlifters, who may have been given drugs without their knowledge, and a fifteen-year-old. [12]

In November 2015, the Independent Commission of World Anti-Doping Agency (WADA) found out that Rodchenkov was “at the heart of the positive drug test coverup”, in particular, he requested money from athletes for concealing positive tests and violated WADA directives by destroying 1,417 urine samples. Rodchenkov made headlines in 2016 after an interview to The New York Times exposing a state-run doping program in Russia. Rodchenkov said he developed a three-drug cocktail of banned substances that he mixed with liquor and provided to dozens of athletes at Sochi Olympics. Rodchenkov’s allegations were confirmed by the independent McLaren Report, leading to Russia's partial ban from the 2016 Summer Olympics and total ban from the 2018 Winter Olympics.
