Dwain Chambers has won the 100 meters at Britain’s Olympic trials.

Chambers, who is returning from a two-year drug ban, finished in 10.00 seconds in Saturday’s final, and now hopes a judge will overturn his Olympic ban.

He goes to London’s High Court on Wednesday to seek an injunction against the British Olympic Association’s lifetime ban on drug cheats.

Britain has to name its Olympic squad by July 20.
