“I wasn’t really worried about Justin. I knew if he got the baton in front of me, I could catch him,” Usain Bolt said. “So it was just going out there to run as fast as possible.”
With this win, Usain Bolt becomes the person with the all-time highest medal tally at the World Championship games with eight gold and two silver. Carl Lewis is now the second highest with eight gold, one silver and one bronze.
