He said interest in the only Victorian race run in a clockwise direction had never been bigger.

McKenzie said many of the nation's leading trainers potentially had starters.

He said about 25 horses had qualified under the requirement that 2yos trained in Victoria, South Australia and Tasmania were required to trial to the satisfaction of stewards in clockwise jump-outs in Ballarat.

Other nominations are expected from New South Wales and Queensland, where all racing is clockwise.

McKenzie said the feature, which was first run in 2012, had grown to carry as much prestige as the $500,000 Ballarat Cup.

He said it was initially programmed as an experiment, with its main purpose being to give southern state youngsters an opportunity to get experience racing clockwise before the Magic Millions 2yo Classic on the Gold Coast in the new year. While still serving this purpose, the clockwise event now stands up in its own right.

McKenzie said this would be the first running of the event under a new five-year agreement between the BTC and Magic Millions.

He said the partnership had been an outstanding success and would only get stronger.

The BTC had its last three clockwise jump-outs on Thursday, with Ciaron Maher-David Eustace, Mick Price/Mick Kent junior, Gai Waterhouse/Adrian Bott, Anthony Freedman and Team Hayes among trainers with runners.

Euphoric Summer won for Price Kent, Soul Obsession for Freedman and La Girl for the Hayes camp.

Euphoric Summer has had just the one race start, finishing second in the listed Inglis Debutante Stakes, 1000m, at Caulfield on October 12.

The filly sold for $260,000 this year's Gold Coast MM Yearling Sales.

An unraced filly, Soul Obsession went under the hammer for $175,000 and La Girl for $360,000 at the same sale.

La Girl was fourth on debut in the listed Darley Ottawa Stakes, 1000, at Flemington on Melbourne Cup Day.
