Ed Walker may give Tonyx more experience at novice level after the three-year-old filly romped home by eight lengths on her belated racecourse debut at Salisbury.
The Upper Lambourn trainer will look to step up the daughter of Nathaniel up from a mile and a quarter to a mile and a half, should she go to Ascot on October 4.
“She might run back in a mile-and-a-half novice at Ascot in a couple of weeks,” he said.
“She only came to me a couple of months ago. She was at pre-training and was a late-maturing filly, and came into me in good nick.”
Tonyx’s hugely impressive debut performance, at 25-1 two weeks ago, was nonetheless a pleasant surprise.
Walker added: “She looks like being quite a nice filly.
“She had done a couple of pieces of work that we thought were nice.
“I felt she would need a bit further than that, and I didn’t expect her to win that emphatically. But she’s a galloper and she relaxed nicely and powered up the hill at Salisbury.
“I think she will get further, and I’m very happy with her.”
