Summary The CAS banned Brazilian runner Simone Alves da Silva for five years for using EPO.
The Court of Arbitration for Sport banned Brazilian runner Simone Alves da Silva for five years for using EPO when breaking the South American 10,000-meter record by 31 seconds.
CAS says da Silva s ban runs through to October 2016, ruling her out of the 2016 Rio Olympics.
Da Silva s positive test after racing in Sao Paulo in August 2011 was her second doping offense. She previously served a three-month ban for using the stimulant Oxilofrine.
The International Association of Athletics Federations appealed to CAS after two Brazilian sports tribunals cleared her.
The CAS ruling published Wednesday said da Silva claimed her urine sample was spiked while she did a television interview accompanied by doping control chaperones.
Her lawyers also challenged a handwriting error in laboratory paperwork.
