The trainer of Australia's greatest racing hero of modern times will ease his way out of the sport over the next few years to indulge his passion for military history.

Peter Moody, the man who has trained Black Caviar to win 22 races from as many starts, said he will begin an odyssey in May next year by walking the Kokoda Track in New Guinea and then explore the battlefields of south-east Asia and Europe.

"I'm not a bloodthirsty bastard, but I'm very proud of the Australian war history and its something I want to do," Moody revealed.

"It's something I want to bring into my life over the next three or four years as I get sick of getting out of bed at three o'clock in the morning."

Moody's plan obviously requires some changes to his life that he is prepared to make, including walking away from his position as the country's most successful trainer.

He says he has always planned to cut back on the level of his involvement in the industry that has made him a household name, but he would like to continue to prepare horses, possibly as a private trainer.

Moody's announcement follows the decision last week to continue the career of Black Caviar who suffered a variety of injuries on her trip to England earlier this year.

The standard line was that the champion mare suffered injuries during the running of the Diamond Jubilee Stakes at Royal Ascot, but Moody revealed she had been troubled before the race.

"I knew we were in a bit of trouble a little way out," he said.

"But I thank the fact that she is the champion she is and was able to carry us all through."

All being well, Black Caviar will resume racing next autumn with the intention of making a farewell tour of the eastern states.

"My dream is for her to come back in the autumn and give her a run in at least Sydney, Melbourne and Brisbane in a farewell tour," he said.

"It would have been much easier to retire her, but I always wanted to see her finish her racing here at home.

"I'm very mindful that she's 22-from-22 and the important thing now is to protect that record."

Black Caviar is likely to resume in the Lightning Stakes at Flemington in February.
