Russian Track Team banned by IAAF from Rio Games/Russian doping scheme from London games throughout Sochi games

In November 2015, the IAAF banned Russia's Track and Field team from competing due to state sponsored doping at the 2008 Beijing games, 2012 London games and now evidence has come out that Russian athletes were doping at the 2014 winter games in Sochi. These Russian track and field doping allegations were uncovered by a World Anti Doping Agency(WADA)investigation that involved the former head of the IAAF- Laminme Diack. Diack was paid by Russian officials to cover up positive doping tests by Russian athletes that would allow them to continue competing. Diack was suspended by the IAAF in November 2015 and stepped down from the IAAF a day later. Diack was arrested by French authorities for corruption and money laundering shortly after. Diack hired his son to work at the IAAF and brought in other advisors as part of a " powerful rogue group" that corrupted the IAAF from the inside. The WADA report does not name current IAAF President Sebastian Coe in any of the allegations but the report did hint of Coe being part of an Oversight body which was blamed in the report. Coe was the Vice President of the IAAF under Diack and took over the IAAF as President in August 2015.

Russia's track and field team was suspended in November 2015 by the IAAF. This ban could have been lifted by the IAAF if Russian officials were to reform their anti doping measures and to make reforms to its anti-doping agency. Nikita Kamaev, former head of Russia's anti doping agency was found dead within two months after resigning from the agency and the head of Russia's anti-doping agency ahead of the 2014 Sochi games, Grigory Rodchenkov, after being forced to resign by Russian officials, fled to the United States for protection after being called out by the WADA for allegedly extorting money from athletes and covering up tainted urine samples with clean ones. On June 17, 2016 the IAAF banned Russia's Track and Field team from the Rio games, essentially keeping the suspension in place. The IOC has backed the IAAF's decision to ban Russia from the Rio games, although there is talk of letting certain Russian track and field athletes compete under an Independent entity but not under the Russian flag. These athletes would have to be tested frequently. So far 67 Russian athletes have submitted their application to compete in Rio.

In May 2016, more allegations of Russian state sponsored doping surfaced. 15 Russian Sochi games medal winners, mostly on the Russian Cross Country Ski team, were part of an elaborate doping scheme by the now former head of the anti-doping agency, Grigory Rodchenkov to replace tainted athletes urine samples with clean ones that were collected months earlier. At least 100 samples that were tainted with performance enhancing drugs were destroyed as Russian athletes were able to test negative and medal at the 2014 Sochi games. Rodchenkov developed a cocktail of steroids that escaped detection leading up to the 2012 London games to throughout the 2014 Sochi games. This was an elaborate plan to perfect Russian athletes from all sports in both the winter and summer games. This was approved at the request of the Russian government. The current head of the Russian anti-doping agency, Vitaly Mutko has denied these allegations. Investigations are ongoing.
