Jamaican sprinter Usain Bolt wants to secure four gold medals at the London Olympics next summer.
Bolt wants a spot on the Jamaican 4x400m relay team to achieve his medal dream ,while he also has his sights set on retaining the 100m, 200m, and 4x100m gold medals he picked up at the Beijing Olympics in 2008.
He said: "I've expressed that to my coach. If I am fit and I think I can do it (the 4x400m relay).
"I definitely would want to try because if I do as well as in Berlin, the 4x4 would top it off and even make it a little bit much better.
"I will probably be in good shape and I know the guys are really stepping up the 400 level in Jamaica."
Bolt's best recorded time in the 400m is a fairly unimpressive 45.28 seconds, although his trainer claims he ran a 43-split after a running start in a minor meeting in Jamaica two years ago as part of a relay team.
