Usain Bolt could be about to make Olympic history *again* as he goes for gold with his Jamaican teammates in the relay.
The superstar sprinter has already cruised his way to gold medals in the 100 and 200m.
But now he'll have to count on his Jamaican teammates to help him complete the collection.
If he manages it, it will be the third time in a row that he's got all three gold titles at the Olympics - that's why it's called the 'treble treble'.
Can he do it??
