"I wasn't worried," he said of the 200m. "I knew I had to get through the 150 first and I ran my hardest and got it done -- after the first 150 I looked across and I could see that Justin Gatlin was tired so it was never a doubt that I was going to win the race."
These were the words of Usain Bolt has cemented his legendary status after winning his 11th individual world or Olympic sprint title from a possible 12 since he took track and field by storm at the 2008 Beijing Olympics.
The 29-year-old Jamaican shot to fame seven years ago at the Bird's Nest when he blasted to victories in the 100 and 200m before going on to anchor his 4x100m relay for a third gold.
He repeated that feat at the London Olympics and has also swept all world titles in Berlin in 2009, Moscow 2013 and now in Beijing, his only blip in the Daegu 100m in 2011 after a false start.
On Thursday, Bolt clocked a world-leading 19.55 seconds to beat Justin Gatlin by nearly two-tenths to add the 200m to his 100m title.
Bolt's phenomenal prowess belied a tricky season in which he sat out six weeks of competitive sprinting because of pelvic joint pain.
But he insisted that the 200m was his baby and that he had been riled by pre-race comments from Gatlin, who has served two doping bans but is in the form of his life at the age of 33.
