Usain Bolt is still the world's fastest man. 
The Jamaican sprinter lived up to his name and reputation when he came in first place in the men's 100-meter final and secured his place in history as the first sprinter, man or woman, to ever take three consecutive gold medals in the 100. Team USA's Justin Gatlin, Bolt's closest pursuer over the past four years, finished second, .08 seconds behind. Andre de Grasse of Canada won the bronze.

Bolt's win is especially remarkable considering that he hasn't run a 100 since June 30, when he had to pull out of the Jamaican national championships with a bad hamstring. It seems like the weeks of rehab worked like magic and Bolt showed no sign of injury on the straightaway. Gatlin's silver is no less remarkable: at 34, he's the oldest Olympic medalist ever to compete in the men's 100.

Fans are flooding Twitter to share their feelings about the highly-anticipated race:

Bolt will go on to qualify for the 200 on Tuesday, and — in all likelihook  — go for another gold in that final on Friday.
