Muscled-up gelding Gojo Mimo's reputation as one of Queensland's fastest horses out of the barriers will be tested with his return to city racing on Saturday.

Gojo Mimo will be having his first start in metropolitan class since November when he tackles the Herbert Smith Freehills Handicap (1000m).

It will be one of the highlights of Saturday's racing as Gojo Mimo has won both his runs since a spell with displays of sustained speed at Ipswich and the Sunshine Coast.

Both times he has bounced out of awkward barriers and led for comfortable wins in smart time over 1000m.

The jury is out on whether he can repeat those performances against a field of hardened city-class horses.

But trainer Brad Herne is confident Gojo Mimo has returned a much stronger horse.

"I think it is one of the reasons he is now getting out of the barriers so quickly. He looks stronger and he is starting to live up to the promise we always knew he had," Herne said.

"We have had this race in mind for him right from the start of this campaign. I think 1000 metres is ideal for him at the moment but I have no doubt he will eventually run a strong 1200 metres."

Herne said Gojo Mimo was ideally drawn at barrier two on Saturday in a much tougher field than the gelding had faced.

"There are a couple of really tough old short-course horses in the field so it will give us a good guide to where we are at," he said.

Jockey Ashley Butler, who rode Gojo Mimo at his last win, will ride the gelding at 54kg.
