My coach makes me laugh, says Bolt

The 26-year-old swept both sprints to become the first athlete to win back-to-back 100 metres and 200 metres titles at an Olympic Games, following his success in the Beijing Olympics four years ago.

"I want to give thanks to Glen Mills. He is the greatest person; he has been a father figure, my mentor, he's been a coach and for me he is the person that makes me laugh," Bolt was quoted as saying by CMC Wednesday.

"He's truly a great person overall. He is the greatest coach ever."u00a0
