Perkins shaved almost four seconds off the previous record of 7:38.75, held by Germany's Michael Gross. Perkins, the Olympic 1500m champion, broke his own 1500m record earlier in the series and now holds world records for both distances in long and short course categories.
His coach John Carew said Perkins had set out for the record. 'We were either going to have a go at the 800 world record here or at the Pan Pacific Games next month,' he said.
'I said to him if he was too slow at the 400-metre mark, I didn't want him to bust a gut and not achieve anything. But he was well under when he went through so he just continued on. It was a big thrill for him.'Reuse content
