Rio de Janeiro, Aug 9 (IANS): Jamaican sprinter Usain Bolt aims to claim a new 100-200-4x100 triple win in Rio Olympics and will try to smash the 200-metre world record.

Bolt on Monday insisted that he will put the finishing touches to his Olympic career in the Brazilian city, Efe news reported.

"This is my last Olympics, for sure. I have done everything, and have proven myself. A lot of people aren't happy," said Bolt.

In a bid for a golden farewell to the Games, the 'Lightning Bolt' will seek a third consecutive win in the 100-metre, 200-metre and 4x100 relay, although his new challenge is to beat the 200-metre world record that he himself set at 19.19 seconds.

Bolt explained that the 100-metre sprint is not stressful but he feels nervous in the 200-metre race.

"I really, really, really want that one," said the Jamaican, referring to breaking the 200-metre world record, which he aims to destroy in less than 19 seconds.
