For the
2004 Summer Olympics, Thanou was one of the main hopes of the home crowd for winning an athletics medal. However, on the day prior to the opening ceremony, Thanou and her training partner
Konstantinos Kenteris failed to attend a drugs test, and later the same night were hospitalised, claiming they had both been injured in a
motorcycle accident. In the ensuing
doping scandal, Kenteris and Thanou announced their withdrawal from the Games on 18 August after a hearing before the Disciplinary Commission of the
IOC, for what they described to be "in the interests of the country." An official Greek investigation into their alleged accident ruled that it had been staged and the pair were criminally charged with making false statements to authorities. The missed test in Athens was the duo's third violation of the summer and they were consequently provisionally suspended by the
IAAF on 22 December 2004. In June 2005, however, the athletes were cleared of all charges by the Greek athletics federation. Their coach
Christos Tzekos was blamed for the missed tests and suspended for four years, but was cleared on separate allegations of distributing banned substances. After a long legal battle, on 26 June 2006 prior to a final ruling by the
Court of Arbitration for Sport, the athletes reached an out of court settlement with the IAAF accepting anti-doping rule violations of 3 missed tests between 27 July and 12 August 2004 (in breach of Rule 32.2(d)) and a failure to provide
a urine and a blood sample on 12 August 2004 (in breach of Rule 32.2(c)). In return, the more serious charges against them, those of evasion and refusal to provide a sample, were dropped. They have been eligible to compete since 22 December 2006. ==Return from suspension==
