Usain Bolt declares he will 'definitely' win in Rio after his win in the 100m event at the IAAF Golden Strike meet in Ostrava, Czech Republic on Friday (20th May).

SOUNDBITE (English) Usain Bolt, 100m winner (on winning in Rio):

Q: Can you promise all the Japanese fans.... (unintelligible)

"Definitely, I'm definitely going to win in Rio. For me, as long as I get everything right and everything goes smoothly I should be OK, you know what I mean"

SOUNDBITE (English) Usain Bolt, 100m winner (on his race start):

"My start...overall my reaction was good. I think the only problem I had was the power behind the start wasn't there. I didn't execute, I didn't get the power through the first 40 so I had to work a little bit harder at the end to get up to speed so if I can improve that then it should be OK."
