Rio 2016 on TV: Men's 200m final
UK start time: 2:30am Friday
Usain Bolt already has 100m Olympic gold, and looks in fine form for tonight's 200m final. He ran his fastest time of the year to win the semi-final in 19.78 seconds – and he looked like he was cruising.
His main rival, Justin Gatlin, will not be in the 200m after he failed to finish fast enough in his own semi-final.
Team GB's Adam Gemili however will be on the start line for the final as one of the fastest losers.
But Bolt won't be easing up tonight: he's aiming to break the 200m world record. Best set that alarm clock...
