Jamaican sprinter Usain Bolt participated in the red carpet yesterday for the premiere of a new film about his career.

Olympic gold medalist nine times, Bolt shows his exhaustive workouts and competitions in the documentary.

'I Am Bolt' includes footage from the Beijing World Championships and London and Rio Olympics; and also shows Bolt's youth and interviews with family, friends and coach.

He wanted to show the hard work behind the success of being the star sprinter: "That's what I wanted people to see, the struggles, the pain, the triumph, the stress that I've been through and then have more insight also on my life."

"I wanted to make people see what I went through to get to where I'm at today.”

The 30-year-old said he plans to retire from the sport after the World Cup in London in August next year.
