Usain Bolt Clinches Gold In Men's 100m At The 2012 London Olympics With New Olympic Record [PHOTOS]

Jamaican sprinter Usain Bolt proved it once again that no one can touch the finishing line faster than him. The world record holder and the defending Olympic champion clinched the gold medal in the 2012 London Olympic Games Sunday and retained the men's 100m title with an electrifying performance.

Bolt, 25, crossed the finishing line in just 9.63 seconds, breaking his own Olympic record of 9.69 seconds that he set at Beijing in 2008. His performance at London Olympics was just .05 seconds short of the world record time of 9.58 seconds that he himself set at the World Championships in 2009.

"A lot of people doubted me," The Washighton Post quoted Bolt saying. "There were a lot of people saying I wasn't going to win. There was a lot of talk. For me, it was an even greater feeling to come out, defend my title and show the world I'm still No. 1. I'm still the best."

Bolt's Jamaican compatriot and training partner Yohan Blake, who had long been tipped as Bolt's successor as the fastest man in the world, won the silver medal with the personal best of 9.75 seconds, while the 2004 Olympic gold medalist, USA's Justin Gatlin claimed the bronze medal with 9.79 seconds, his personal best too.

Tyson Gay and Ryan Bailey of the USA were placed fourth and fifth with a time of 9.80 and 9.88 seconds, respectively.

Prior to the London Olympics, questions had been raised as to whether Bolt could win his second Olympic gold in the men's 100m race, given the fact that his teammate Yohan Blake beat him in both the 100m and 200m races at the Jamaican Olympic trials this year.

Bolt, who had back problems too, won his semifinal heat quite easily. However, his time put him in Lane 7 of the 100m final beside Gatlin in Lane 6, Blake in 5 and Tyson Gay in 4.

But in the final, Bolt put all these speculations to rest and raced ahead to retain his crown as the fastest man on the planet.
