Usain Bolt
Bolt claimed his seventh world title in the 200m

Usain Bolt enhanced his claim to be considered the greatest sprinter in athletics history by storming to his 13th major title in the 200m at the World Athletics Championships in Moscow.

Bolt ran 19.66 seconds, the fastest 200m of 2013, to finish ahead of fellow Jamaican Warren Weir and American Curtis Mitchell, who took silver and bronze respectively.

Adam Gemili, who had earlier qualified for the final with a personal best of 19:98 seconds - the second fastest British 200m of all-time, was edged into fifth.

"The 100m is for the fans, and for the show as the fastest man in the world, but for me it means more to come here and defend my 200 title," Bolt said.

"When I entered the straight, I felt tired; my legs felt a little heavy. And my coach told me not to push too hard if it was possible, so I backed off a little."

The 18-year-old Gemili, the European Under-23 100m champion, was the latest highlight for Britain in Moscow, which continued its impressive record on the penultimate day with bronze medals for Tiffany Porter in the 100m hurdles and the GB quartet in the 4x400m relay team.

"I was very close to a medal - just four hundredths and I missed out on the Olympic final (in London last summer) by four hundredths as well, so it's always those fours," Gemili said.

"But as I get older and stronger that will hopefully come down and down and down. Hopefully I'll be up there getting a medal in future years.

"It's an unbelievable experience to be in that final on the outside of Usain Bolt and just being in the top eight and finishing fifth. I'm just very proud, very happy and very grateful to be in this position.

"It was just after Bolt was introduced and the whole stadium erupted and I thought: 'One day hopefully I'll be in that position.' It puts a smile on my face and helps me stay relaxed."
