Rising star Londehero's Group prospects will be clearer after he competes against older horses for the first time at the Gold Coast on Saturday.

Trainer Matthew Dunn admitted he was in a quandary with Londehero after he lumped 59kg to beat a field of handy three-year-olds over 1200m at Eagle Farm two weeks ago.

The gelding ran a smart 1.09.34 on a day when times were generally below average.

He was entered for the Hot Tomato Saturday Morning Moyra Plate (1200m), a set weights class six race, and the $100,000 Gold Coast Stakes (1200m) for open company horses with Dunn opting for the former.

"In the end he looked too well placed under the Plate scale," Dunn said.

"He is probably the top-rated horse in the field but gets in with just 53.5 kilos."

While the Plate is a softer option, it still boasts a field of hardened older horses.

"There are some very experienced runners in the field but I would be disappointed if Londehero doesn't race very well," Dunn said.

Jockey Glen Colless, who rode in a State Of Origin race in Western Australia on Thursday, has a high opinion of Londehero and will get down to the race minimum to ride him.

After Saturday the gelding will go for a short break before returning for a winter campaign in Brisbane.

Dunn considered a Sydney autumn carnival assignment for Londehero but said the programming of the three-year-old races was unsuitable.

"I think Londehero will get 1400 metres at least but I don't know if he could handle it now," he said.

"It won't be a long spell. Just a short ease up so we can get him back and set him for some better races."

A son of new Australian Hall of Fame inductee Lonhro, Londehero has won three races, all over 1200-metres.
