Usain Bolt was encouraged by his performance at the Anniversary Games in London, after he took victory in the 100 metres in 9.87 seconds.
Six-time Olympic gold medallist Usain Bolt conceded he still has work to do to return to top form, but was satisfied with his 100 metre win at the Anniversary Games in London on Friday, July 24, 2015.
The Jamaican has struggled for form and fitness throughout 2015, and was yet to run under 10 seconds in the 100m before this meeting at the Olympic Stadium.
With the World Championships in Beijing a month away, Bolt was looking for a strong display on a damp night in England's capital.
Bolt ran 9.87 seconds in winning his heat, easing up at the end to raise hopes of an even quicker time in the final.
It was not to be, however, the Jamaican getting off to a bad start before eventually powering through the second 50m and taking the win ahead of Michael Rodgers and Kemar Bailey-Cole in exactly the same time.
"Overall, it was a good run," Bolt told BBC Sport. "My start was really poor. My coach keeps telling to me relax. I want to run faster and it is getting there.
"The first race was very smooth and I was very happy with what I did. In the final, I got a bad start and it all went downhill from there.
"It is hard work and dedication. I just need to keep pushing myself. I feel pretty good. If I continue to work on my start, it will all be good.
"I really love this crowd and I enjoy competing here. One of my most favourite moments was the 200m in London in 2012."
