Aussie walker Tallent wants upgrade to gold

Australian race walker Jared Tallent, an Olympic silver medalist behind a drug cheat, has reiterated his demand that the IAAF award him the gold medal in the wake of an explosive report into systemic doping in Russian athletics.

A World Anti-Doping Agency special commission reported allegations of widespread corruption and collusion by Russian officials, including state security services, to cover up results of drug tests, destroy samples and intimidate laboratory staff.

At London 2012, Tallent finished second in the 50km walk behind Russian Sergei Kirdyapkin, who was found guilty of doping earlier this year and handed a three-year, two-month suspension by Russia's anti-doping agency.
