Champion mare Jameka is another step closer to making an incredible comeback to racing after successfully completing a jumpout at Caulfield on Tuesday morning.

The 2016 Caulfield Cup winner finished fourth in the five-horse trial over 800 metres and will improve significantly fitness-wise off the back of the jumpout.

Whether or not she will return to racing will be determined by trainer Ciaron Maher and her connections after she contests an official trial at Cranbourne on the 6th of August.

"She was pretty fresh and keen, she got out of the stalls pretty well and got into a rhythm," Maher said.

"There were some slick horses in that trial and it looked like they quickened away from her up the hill.

"But Mark (Zahra) knows her really well and he was happy with her action and the way she trialled and I think she'll take a lot from that sort of trial under race conditions.

"It was probably all we wanted to see this morning, she'll come on from that and she can go to the Cranbourne trials on Monday week.

"The deciding trial will be the next one over a bit of ground on a good surface at Cranbourne and we can really open her up to see if she's got the fire in the belly."

Jameka battled a nasty bout of travel sickness that almost claimed her life after her win the Group 1 BMW last autumn.

She was sold to part-owners Colin and Janice McKenna at this year’s Magic Millions Broodmare sale for $2.6 million.
