After spending his life wearing different racing hats, Lewis Seib is giving himself a chance to train a city winner.

He is set to bring Tudor Sunrise to the Highway Handicap (1400m) at Randwick on Saturday, the first week the race will be worth $60,000.

Seib was a foreman for Brian Mayfield-Smith when he trained from Nebo Lodge at Rosehill and later worked for Paul Messara and stud farms at Scone .

With his children grown up - including daughter Danielle who is Seib's track work rider - he decided to open his own stable at Muswellbrook.

"She's a very good track work rider and horsewoman," Seib said.

"It's a big asset to have her."

Tudor Sunrise was trained by Greg Bennett before part-owner Keith Williams decided to send her to Seib.

The mare is one of six horses in the stable, soon to joined by two more.

Seib said Tudor Sunrise had encountered bad luck at her past two starts at Gosford and Rosehill, where she was a fast-finishing fourth in a Highway race over 1200m on July 16.

"She needs room," he said.

"When she ran that good fourth at Rosehill she got to the outside but a bigger track to wind up will suit her a bit better."

The winner of that race, Star Shaft, shifted out in the final stages of the race and Tudor Sunrise was at the end of the chain of horses to be inconvenienced.

While some trainers heading to Randwick on Saturday will be nervously watching Sydney's skies, Seib hopes the predictions of more rain are right.

"She loves the wet," he said.

"On a very heavy track at Mudgee she won well. I think the wetter the better for her."

Seib said Tudor Sunrise's fitness should mean she would have no problem with the 1400m.
