The $450,000 event has moved forward from its traditional January slot to November 10, with the Retravision-Fremantle Cup moving back to April.

Radley said the WA Pacing Cup's move to November ensured there would be feature racing for all horses in that timeslot.

"It's the best time of the year," Radley told TABradio.

"It's when racing comes to the fore in many states, and we are seeing jurisdictions are wanting to get into that space to maximise their returns.

"We build from the two-year-olds to the three-year-olds, the mares and the four-year-olds and the Free-For-All horses are racing at the same time."

The Golden Slipper, WA Derby and WA Oaks moved to a new spring timeslot last year and was followed by the Mares Classic and Golden Nugget.

This year's Golden Slipper is scheduled be held on September 29, with the WA Oaks and WA Derby scheduled for October 13 and November 3 respectively.

Radley said another key factor in the cups changing timeslots was the hope for stronger turnover.

"We tried to look and make sure we are getting the most out of our races," he said.

"The simple thing is the January cups just aren't performing.

"The Nullarbor was in the top half a dozen races of all time in WA, as far as turnover is concerned."

Speaking on the change, trainer Ryan Bell said a decision was imminent on whether Shockwave would continue his winter campaign, or head to the paddock ahead of a spring preparation.

"We've had no set plans for him," Bell told The Trots WA.

"The whole idea of bringing him in for these races was to give him some conditioning for the summer.

"Whether he goes out for a break now, or has another run, it doesn't change much for him.

"I like the idea of splitting the Cups up because they've been pretty much the same races over the last few years."

Shockwave narrowly beat the Greg and Skye Bond-trained Mighty Conqueror in last Friday's Free-For-All at Gloucester Park and survived a protest after the race.

Much like Shockwave, Greg Bond said the change in dates didn't significantly impact Mighty Conqueror and other open class pacers in the stable.

"My view is if something like this is better for the industry, I'm all for it," Bond said.

"We've still got five months to get our horses ready for the Pacing Cup.

"You also have to look for ways to enhance the Nullarbor and tacking on the Fremantle Cup a week after it can hopefully make it better."
