David Vandyke admits he has changed his mind in an attempt to salvage something out of Arabian Gold's autumn campaign.

Arabian Gold will be an acceptor in the Lord Mayors Cup at Rosehill on Saturday in a move that Vandyke concedes would have been the most unlikely of three possible scenarios as he aimed the mare at the Queensland winter carnival.

Bookmakers made Arabian Gold one of the favourites for the Hollindale Stakes, the key lead-up race to Saturday's Doomben Cup.

But her Queensland campaign unravelled when she finished worse than midfield in the Group Two race at the Gold Coast.

"You can watch the race and if you didn't know her you can think `that wasn't a bad run'," Vandyke said.

"But knowing her and watching her during the race I knew she wasn't where she needed to be to progress into a Doomben Cup.

"I thought `you need to go to the paddock and we'll get you back home'."

Arabian Gold return to Vandyke's Sydney stable as a stopover before heading to a spelling farm but the trainer cancelled the horse transporter when her demeanour changed for the better.

"She was jumping around and feeling happy to be home and I thought I just might wait a few days and reassess things," Vandyke said.

"We worked her on Saturday and she worked terrific."

Arabian Gold is equal 59kg topweight with the Bagman, one eight entries in the Cup from Chris Waller's stable.

Ecuador, which missed out on the Hawkesbury Gold Cup on Saturday when set to run favourite has 57.5kg, along with the Godolphin middle-distance performer Malice.

Arabian Gold developed a corn during the Sydney autumn carnival but she recovered in time to run an eye-catching race when sixth in the Doncaster Mile last month.

She is closing in on $1 million in stakes and a second placing on Saturday will ensure she becomes the first horse trained by Vandyke to reach the prize money milestone.
