Bolt is the world's fastest at both 100m and 200m this year
World 100m record holder Usain Bolt believes he can win an individual sprint double at the Beijing Olympics.
The 21-year-old will compete in both the 100m and 200m at the Jamaican trials in Kingston this weekend.
"It would be a great feat to be double gold medallist in the Olympics, it would be a big thing," Bolt told BBC Radio 5 Live.
"A lot of people say I can do it and I know I can, so I will definitely be going out there to win."
Bolt is yet to make a final decision as to whether to compete at both distances in Beijing, although he says the likelihood is he will.
"My coach (Glen Mills) just wants to see where I am right now (before making a final decision) because we haven't done a lot of 200m training," said Bolt.
"I think he's just waiting for me to see what I can do over 200m."

The Jamaican is the fastest in the world over both distances this year after setting a new 100m world record of 9.72 seconds in New York on 31 May and clocking 19.83 at 200m in the Czech Republic on 12 June.
He will be up against his close friend Asafa Powell, who held the previous 100m world record, at the Jamaican trials.
"I've been telling people there won't be a clash (between he and Powell) because it's the trials," added Bolt.
"We're just going there to make the team. If I get third place to make the team, it's ok with me.
"We are good friends, we hang out, we go to races in Jamaica, we go to parties sometimes together."
The Bay Area Laboratory Co-operative (Balco) scandal - in which the California-based company became infamous for a sideline in performance-enhancing drugs - and the subsequent bans imposed on Justin Gatlin, Tim Montgomery, Dwain Chambers and Marion Jones have cast a shadow over sprinting in recent years.
Yet Bolt says he is not concerned about any rumour or innuendo regarding his own performances and insists he is clean.
"When you break the world record, people start saying stuff but it doesn't matter to me," insisted Bolt.
"When you know you're clean, it doesn't really bother you. I know I am working hard, so I have to assume they (other athletes) are working hard also.
"I see Asafa all the time, so I know he's good. He trains hard and works hard, so I know he's clean and is doing the hard work every day.
"We know there are athletes out there who work hard for what they want."
