Usain Bolt has won the gold medal in the men's 200 metre final at the Rio Olympics.
In the warm-up area, a few hours before the race, Bolt looked incredibly relaxed, dancing and shaking hands with people.
Once the athletes came out to race though, game faces were on.
As expected, Bolt stormed to victory in 19.78s, leaving the rest of the field to fight it out for the silver and bronze.
Canada's Andre de Grasse and France's Christophe Lemaitre took silver and bronze respectively.
Bolt took repeated bows to the crowd once the race was won, soaking up the moment at his last Olympic 200m final - he has confirmed he will not be in Tokyo for the next Games.
While everyone enjoyed the unparalleled greatness that is Usain Bolt, people did spare a thought for Adam Gemili, who narrowly missed out on a medal.
Gemili's time of 20.12 matched that of Lemaitre, but he was edged out by a matter of thousandths of a second.
He told the BBC he was "heartbroken" that he so narrowly lost out.
Bolt's latest victory keeps him on course to secure a historic "triple triple" by winning the 100m, 200m and 100m relay three Olympics in a row.
