Dwain Chambers will make his first outdoor appearance on home soil for almost two years on Sunday when he competes for his club, Belgrave Harriers, at the British League meeting in Birmingham.
The 30-year-old former drugs cheat, who has announced his intention to challenge his lifetime Olympic suspension, is expected to compete for his team in the 4x100?metres relay at the Alexander Stadium.
Chambers, whose last outdoor run on home soil was also at the same venue in August 2006, is scheduled to run in a guest 100m at the meeting.
Following his two-year ban for using the designer steroid THG, he initially pursued an unsuccessful American football career.
Then in January this year, Chambers controversially returned to athletics and showed he still possesses massive talent by sharing the World Indoor Championships 60m silver medal with Kim Collins.
Chambers then attempted to forge a career in rugby league with Castleford, which did not work out because of his inexperience.
The Londoner made his comeback to outdoor competition by winning over 100m into a strong headwind at the Kalamata International meeting in Greece on Wednesday night in a time of 10.25seconds.
That performance gave him the qualifying standard to compete in next month’s National Championships, incorporating the Olympic trials, which are also being staged in Birmingham.
Chambers, if he should win the trial race, would normally be automatically included in Team GB for the Olympics, where the track and field action gets under way in Beijing on August 15.
But under a BOA bylaw, any athlete who has served a drugs suspension is ineligible to represent his country.
Chambers said: “I’m optimistic I will be in China. The ruling is unfair and this only exists in Britain. I don’t want to put my country in a difficult position, I’m doing this because I believe I can do well in the Olympics.
“If I didn’t believe that then I wouldn’t waste my time and the time of my lawyers.
“What has happened, has happened and I can’t change it now. For me it’s important that the public support me and I have been very encouraged by that.”
It is likely proceedings, which will be the first stage in his legal action, will be issued by the end of next week.
