Reigning triple Olympic Champion Usain Bolt's first final was the men's 100m on 5 August despite being Olympic champion and world record holder many doubted Bolt's form and fitness as he had come second in the 100m and 200m at the Jamaican Championships to his training partner the world 100m champion Yohan Blake. Despite the doubters Bolt blazed to gold in 9.63 breaking his own Olympic record with Blake taking the silver in an equal personal best of 9.75. The win meant Bolt became the second man in history to defend the Olympic 100m title.
