Dwain Chambers will be able to defend the World Indoor title in Istanbul next month after a hard-fought success at the Aviva UK Trials and Champion-ships in Sheffield.
However, the 33-year-old said he has one eye on the London Olympics ahead of a court case that will decide if he can compete on home soil this summer.
The British Olympic Association will argue before the Court of Arbitration for Sport on March 12 that the BOA's bylaw, which bans convicted drugs cheats from competing in the Olympics, does not violate the World Anti-Doping Association code.
Chambers, cyclist David Millar and other athletes convicted of doping offences are ineligible to compete at London 2012.
But if CAS find the BOA's bylaw to be non-compliant with the world anti-doping code, they will be cleared to be selected for Team GB.
"That is in my mind but it's out of my hands," said Chambers after winning the 60 metres title in 6.58sec, just holding off 21-year-old Andrew Robertson (6.61).
"I have to prepare. If the door opens at least I am prepared and I can compete.
"If that does not happen, there is the European Champion-ships in Helsinki.
"No athlete has the green light, we all still have to qualify.
"I talk about the Olympics with the others, although my situation is different. If the opportunity presents itself, I will be able to run beside them."
Chambers lost an appeal against his ban in 2008 and was keen to avoid another court battle. "The climate is different because I am not taking the fight. I don't want to be in court."
