Bolt's Commonwealth aim
Usain Bolt has revealed he wants to compete in the 2014 Commonwealth Games in Glasgow.
The participation of the Jamaican sprint star would be a huge boost for the event's organisers.
Bolt, who retained his 100, 200 and 4x100 metres titles at London 2012, does not have a Commonwealth gold medal, having missed the 2010 Games.
He told journalists in Barcelona: "That's the only title I don't have so I think it's something I'd like to go for, even if I do just one event."
Bolt also reiterated he would continue to concentrate on the 100m and 200m next year rather than trying out the long jump or 400m.
He added: "We've decided with my coach that we're not going to do the 400 or the long jump so it's going to be the 100 and 200.
"It's all about trying to go as fast as possible. Try to stay injury-free, make sure I do my back exercises so I'm strong and I'm ready. That's one of my main focuses now. With 28 and 29 coming up, you start going downhill so I want to get those (fast times) out of the way."
