Usain Bolt has warned rivals he is fit and ready to rewrite the history books at Rio 2016 , which he confirmed will be his last Olympics.
The Jamaican superstar also confirmed his hamstring has recovered in time to run his first 200 metres of the season at the Muller Anniversary Games in London on Friday night.
The six-time Olympic champion faces a key test of his fitness when he races for the first time since pulling out of the Jamaican trials with a hamstring strain.
“I’m good, I’m feeling good, been training good now, I’m happy with where I am,” the 29-year-old said.
“My hamstring is good, I have no issue right now. I know I’m in good shape.”
Bolt returns to the scene of his Olympic gold medal victories at London 2012 in the 100m, 200m and relay.
The 200m run will be his last outing before the Rio Games, starting on August 5, where he be targeting an unprecedented ‘triple triple’ of Olympic crowns.
“I’ll definitely be there, I’m excited to go,” he said on Thursday.
“This is where history is going to be made. I’m excited to put on a show for the entire world to see.
“This is my final Olympics, it’s a big one.”
Bolt is familiar at dealing with, and defying, doubters, especially last year when he went into the World Championships in Beijing trailing two-time convicted drug cheat Justin Gatlin in the 100m and 200m world rankings only to leave China with the complete set of gold medals.
“I’m definitely a tough competitor,” he said. “Last year Gatlin was just not ready, it was the first time he was being chased.
“It was hard for him, but this year is not going to be the same, I am in much better shape, so I won’t leave it to the last second.”
