Ciaron Maher can't fault Caulfield Cup favourite Jameka who has pleased her trainer in a course proper gallop heading into the $3 million race.

Jameka, one of three Cup hopefuls for Maher, worked solo over 1200m on Tuesday at Caulfield and Maher believes there's a lot to like about the mare stepping up to 2400m on Saturday and dropping to handicap conditions.

"We've trained her to peak for her next couple of runs and I think she's improved every start this campaign. And Saturday should be no different," Maher said.
