GEORGE TOWN (Cayman Islands) • World 100 metres and 200m record holder Usain Bolt opened his 2016 season on Saturday with a 100m victory in 10.05sec at the Cayman Invitational.

Making his first strides on the road to the Rio Olympics in August, the Jamaican crossed the finish line 0.07 of a second ahead of American runner-up Dentarius Locke.

"It wasn't the best, but as long as I come out injury-free, that's the key thing," Bolt said. "I didn't feel as smooth as I wanted to, but as I always say, it's hard to just come into your first race and do extra well."

Jamaican Kemar Bailey-Cole, who trains with Bolt at Racers Track Club, was third in 10.18 with a light tailwind of 0.1m/sec.

Bolt is planning his campaign with the aim of retaining his 100m, 200m and 4x100m Olympic crowns in Brazil, seeking an unprecedented third gold medal in a row in all three events in what he has said will be his final Olympics.

The 29-year-old, who races in Ostrava in the Czech Republic this week, said he is not worried about his form.

"It's just more races," he said. "My coach will determine what I need to work on but right now, it's just more races. The more races I run, the better I will feel so I am just looking forward to running more races and see what happens.

"I am never worried. I've been in worse situations. It's just race rusty. I can tell. I could feel the difference from when you are flying from when you are not."

The superstar had not competed since winning three golds at last August's World Championships in Beijing. Bolt, who owns the 100m world record at 9.58 and the 200m mark of 19.19, was off his pre-meet projection of a victory in 9.91.
