Sydney’s premier trainer Chris Waller is adamant he has to keep some speed in leading Caulfield Cup hopeful Royal Descent, reports Racing Network. The 10-length AJC Oaks winner from the autumn resumed over 1400-metres when a gallant second in the Group 3 Toy Show Quality, yet Waller is running the mare second-up again over 1400-metres in Saturday’s Group 3 $125,000 Tramway Stakes, at Randwick.

“I want to keep a bit of speed in her,” Waller told TVN.

“She’s qualified for the Caulfield Cup and she should get into the field OK,” he continued.

“Her semi-final will be the Turnbull Stakes (2000m) at Flemington two weeks before the Caulfield Cup and three weeks before the Cox Plate.

"That gives you options,” he added.

“I don’t know if she can win second-up over 1400 metres, but I’m very aware about keeping some speed in her legs.

"She seems the ideal type for a Caulfield Cup, it’s now about managing her right and getting her there in the best possible condition,” he said.
