British sprinter Dwain Chambers will challenge his lifetime Olympic doping ban in a bid to compete in this summer’s Beijing Games.

On the day Chambers met with Britain’s national anti-doping organisation and handed over a letter detailing the drug regimen that led to a two-year suspension, his lawyer said Friday the runner would seek to compete in the British trials and rescind his lifetime Olympic ban.

“We can confirm that Dwain Chambers will be taking proceedings to secure his eligibility/participation in the Olympic and National trials in Birmingham from July 11-13,” Nick Collins, the athlete’s lawyer, said in a statement.

If Chambers runs in the trials and wins the 100 meters, he will then challenge the British Olympic Association’s rule which bars athletes with doping convictions from competing in any Olympics. The 30-year-old Chambers tested positive in 2003 for the banned steroid THG, and served a two-year suspension imposed by the International Association of Athletics Federations. Collins did not specify whether Chambers would take legal action or file an appeal.

Although there have been 26 successful appeals against Britain’s lifetime Olympic ban in the last 16 years, nobody has challenged the actual legality of the rule in the courts. Chambers could take the case to the High Court in London or the Court of Arbitration for Sport in Switzerland.
