Bathurst's heat will be the first of seven across country NSW, all carrying $100,000 in prizemoney, with the series to culminate at Dubbo on March 22 prior to the $300,000 final being held at Royal Randwick on April 4.

Orange trainer Jeff Brasch says his mare Vortuka is right on top of her game ahead of Sunday's race.

And she'll have to be, after drawing wide and having to contend with stepping out to 1400m for the first time.

"My only concern is the 1400m but she's won over 1300m before and I think she'll run out the trip," Brasch said. "She's drawn a bit awkward, but she'll sit up on the speed. I think she's come back in a lot bigger and stronger this time."

The four-year-old mare is coming off a solid first-up win at Orange over 1000m and despite the quick step-up to 1400m her trainer said he could not fault Vortuka as jockey Nigel Seymour takes the ride.

"I'm very happy with her and she's right at her peak," Brasch said.

"Nigel rode her in a track gallop [earlier in the week] and said she was going well."

The NSW government has thrown its support behind The Championships in only its second year, investing $10 million and ensuring the series is up there with the best in the world.

The Bathurst qualifying race will be the first in a series of seven which will also include Port Macquarie (March 6), Tamworth (March 12), Wagga Wagga (March 15), Grafton (March 20), Goulburn (March 20) and Dubbo (March 22).

Brasch said the new concept had been fully embraced by country trainers and if Vortuka can qualify on Sunday, she'll race for $300,000 in prizemoney at The Championships.

"To be able to race for this prize money against your peers will make this a fantastic day," Brasch said.

"It's a very exciting concept and everyone out here at the track is talking about it."
