Commonwealth Games 100m gold medallist and 100m world record holder Asafa Powell dedicated his sprinting career to two of his brothers who died under tragic circumstances. The 23-year-old Powell took to the tracks five years ago after watching his five older brothers play football and compete on the track. Tragedy struck in 2002, when his brother Michael was shot and killed in a taxi in New York.

Things got worse the following year when another of his brothers, Vaughn, collapsed on a football field and died. "I took it really hard back then, but now I dedicate everything in my career to them," said the Jamaican in Melbourne's Herald Sun newspaper. "I could have quit but I never thought about it because I know they would have wanted me to continue running, so why stop? I've still got too much to do." Powell said he believed his brothers who died were celebrating his gold medal. "They would be jumping all over the place — I am sure they are watching me."
