Three Russian runners banned for 4 years after Beijing retests

Long-distance runner Inga Abitova and 400-metre specialists Anastasia Kapachinskaya and Denis Alekseyev had already been disqualified by the International Olympic Committee last year after their samples from Beijing were found to contain banned substances, including the steroid turinabol.

Alekseyev won bronze in Beijing as part of the Russian men's 4x400-metre relay team, but the IOC ordered that he and his teammates be stripped of their medals.

His results between August 2008 and June 2013 are annulled, the Russian athletics federation said in a statement.

Kapachinskaya and her 4x400-metre relay teammates were also stripped of their silver medals from Beijing. Her results starting from August 2008 are annulled, the federation said.

The suspensions handed to Abitova and Alekseyev will end next year because they include two-year bans they had previously served for doping offences, the federation said.

The International Association of Athletics Federation (IAAF) provisionally suspended Russian track and field athletes from international competition in 2015 over a report by the World Anti-Doping Agency (WADA) alleging rampant state-sponsored doping in the sport.

Russia's track and field team, with the exception of one athlete based in the United States, was banned from the Rio Olympics last summer. The majority of Russian athletes are also set to miss the world championships in London in August.

In recent months the IAAF has cleared a total of 15 Russian athletes, including 2015 world champion hurdler Sergey Shubenkov, for having demonstrated that they are training in an environment that meets its anti-doping requirements.
