The racing future of star colt All Too Hard is in doubt.

Co-trainer Wayne Hawkes said there was no need to rush into a decision but the valuable stallion prospect's blood count was still "not quite 100 per cent" after a minor setback leading into the Australian Guineas at Flemington last month.

He said a decision on where the three-time group one winner races next, or whether he is retired without another start, would be up to the colt's owners.

All Too Hard was scratched from the Australian Guineas because of an elevated temperature.


He was expected to press on to the Sydney carnival but Hawkes said there was no "grand final" race for the colt.

"You've got a Doncaster, you've got Derby and he's not that type of horse," Hawkes said.

"So it's not like you've got a grand final, so to speak.

"It's not that we're in limbo, but we just don't have to rush because he's actually done what he needs to do."

Hawkes said a decision on whether All Too Hard goes to Royal Ascot would be up to the owners.

"If they want to take him on to England, we'll go. And if they don't, we won't go," he said.

Asked if All Too Hard might have run his last race, Hawkes said: "It's up to the owners. He's done his job in life."
