Jamaican sprinter Usain Bolt won gold in men’s 100 meter race with
9.63 seconds, fastest in the history of Olympics. His compatriot Yohan
Blake came second as he took 9.75 second to complete the race. US’
sprinter Justin Gatlin grabbed bronze with 9.79 seconds.
Bolt holds a world record of 9.58 second in 100 meter racing, the
record he set at the Berlin World Championships in 2009. With it, he now
has the three fastest 100 meters in history next to his name. He is
only the second Olympic champion in the 100 meters to defend his title
after United State's Carl Lewis.
