Usain Bolt.

Zurich - Usain Bolt wants to defend his three Olympic titles at the 2016 Rio de Janeiro Games, though he has yet to decide his plans for next season.

Bolt says he's looking forward to Rio and to “really defend all my titles, that would make it even greater.”

Still, Bolt could change his usual program of 100 and 200 meters and 4x100 relay at the 2013 world championships in Moscow or beyond.

Bolt says he'll soon discuss strategy with coach Glen Mills and “I will be saying long jump, he'll probably be saying 400 meters.”

The Jamaican sprint star is unlikely to challenge his 200 world record of 19.19 seconds at the Weltklasse Diamond League meeting on Thursday.

Bolt says: “I just want to go home. I'm counting the days now.”
