Not only is Usain Bolt the fastest man in the world over 100 metres, but he's one of the nicest too.
While he could have been forgiven for enjoying his moment in the media spotlight after another Olympic gold, his third in the event, the Jamaican has been here before.
That's not the case with 400m champ and new world record holder Wayde van Niekerk, who has a long way to go before reaching Bolt levels of fame.
Van Niekerk took gold shortly after Bolt, who - like the true champion he is - ducked out mid-interview to congratulate the South African.

The response only served to demonstrate the love that people have for the Jamaican, who runs again on Tuesday when the 200m heats get underway.

Some have suggested Bolt's 100m record of 9.58 seconds will never be broken, but the new 400m boss has shown that anything is possible in top-level athletics.
