Greek sprinter Katerina Thanou says she wants to return to competition after her recent acquittal of violating anti-doping rules by the Greek Athletics Federation.

Thanou, who was accused of evading doping tests before the Athens Olympics, has denied she ever took illegal substances.

Earlier this month, the Greek Federation exonerated Thanou and Kostas Kenteris of intentionally missing doping tests on the eve of the Games, saying they had not been properly notified. The sprinters had faced two-year bans if found guilty.

The sprinters were temporarily suspended by the International Association of Athletics Federations on December 22. The IAAF said it was "very surprised" by the Greek federation's decision and will review it. It can reject the ruling and appeal to the Swiss-based Court of Arbitration for Sport.

Earlier this month, World Anti-Doping Agency president Dick Pound said WADA would take the case to the CAS if the IAAF does not contest the ruling.
