The Kenyan is competing over the rarely-run distance in the Diamond League meeting, looking to bounce back after disappointment in his farcical last race

After a mix-up at the start ruined his chances on his 2016 Diamond League debut in Shanghai, David Rudisha is keen to show he is back in the shape of his life when he makes a rare appearance over 600m at the Birmingham Diamond League on Sunday (June 5).

The world 800m record-holder was fifth in China after he and other runners weren’t ready when the gun went off.

He could make amends if at the Alexander Stadium in Birmingham tomorrow he breaks the world record of 1:12.81 run by Johnny Gray in 1986.

Speaking at a press conference for the same meeting at which he ran 1:13.71 two years ago, he spoke about the debacle in China last month.

“It was disappointing in my first competition with the confusion,” said the Olympic 800m champion, who had led into the home straight but drifted back after his earlier over-exertion. “I felt I should run an 800m the following day to prove something was wrong. It’s tough when you make such a long journey and everything gets screwed up, but in sport mistakes can happen and it’s not my fault so I’m looking forward to this 600m.”

Having run 45.50 for 400m, he feels he is well suited to the rarely-run one-and-a-half lap distance and ready to go quicker than two years ago.

“In 2014 I was just coming back from injury problems and this year I feel training has been good,” he said. “Training has been going very well so I want to see how far I can push tomorrow.”

With the injuries that followed his remarkable Olympic win and world record in London 2012 now well behind him, he is looking forward to a return to his best this season.

“My training has been better and better every time,” the Kenyan said. “I feel my body is coming back to [as in] my best years.”

Rudisha will line up in the televised event alongside, among others, Frenchman Pierre Ambroise-Bosse and Britain’s Michael Rimmer.
