Campton, who has built a strong stable of 33 at the Gold Coast, is hopeful Lord Markel can repeat his recent Gold Coast win.
The six-year-old came from last in a small field of five to score a runaway five-length win on a heavy track on September 24.
“It looks a winning race again for him on Wednesday,” Campton said.
“He was very dominant at the Gold Coast first-up and he means a lot to us.
“He was my first starter and my first winner the day he ran at Warwick and he’s also my first metropolitan winner.
“I’ve had 12 wins since I started training from about 45 runners.”
Campton was living in Hong Kong when a close friend, Luke Murray, told Lord Markel’s part-owner Kevin Page that he intended to return to Australia to train at the Gold Coast.
“Kevin found out from Luke I was coming back home to train and Kev decided to send up Lord Markel to give me a go,” he said.
“I used to follow the horse in Melbourne and I always thought he’d win some races here in Queensland.
“He’s going enormous now and this prep is the right time to have a throw at the stumps if he wins again so we may take him to Sydney for a Benchmark race in a few weeks.”
