Exeter's Liam Tancock goes for gold at the London Olympics tonight.
He's qualified as third fastest for the final of the 100 metres backstroke.
He's the world record holder in the 50 metres backstroke, which unfortunately isn't included in the games.
Liam's not too bothered about that though, because, even though he faces stiff competition tonight, he's trained hard for the longer distance...
Liam's final takes place just before 8 o'clock this evening.
