Peter and Paul Snowden will head to Rosehill on Saturday looking to build on a season that has exceeded their expectations.

And they hope to do it with a horse who is proof loyalty in racing isn't dead.

In their first full term as a partnership, the Snowdens finished sixth on the Sydney trainers' premiership and made their presence felt in top-level races.

"To get five Group Ones was great and I think we won twenty-something stakes races so we did really well," Peter Snowden said.

Winter Challenge contenders Great Esteem and Disclaimer headline Team Snowden on Saturday but father and son will be just as happy if little-known filly Self Esteem can win.

Self Esteem is raced by a partnership which includes Debbie Kepitis, a daughter of Snowden's former Crown Lodge boss Bob Ingham.

Kepitis was one of the first owners on board when the Snowdens went into business at Randwick.

"It's the old brigade," Snowden said.

"Debbie purchased her (Self Esteem) at the Gold Coast. She was our first purchase so it would be great to see her win a race on Saturday."

Self Esteem was scratched from Canterbury on Wednesday because of a wide gate and hasn't fared much better with barrier 10 of 10 in the Structaflor Yellowtongue Plate.

However, Snowden is adamant the 1400 metres and roomy Rosehill circuit will be in the filly's favour.

He is testing a new theory with stablemate Great Esteem who will head to the Listed Winter Challenge (1500m) on a seven-day back-up for the first time in his career, a tactic the trainer admits is a gamble.

Stablemate and rival, Disclaimer, finished fourth in the corresponding race last year and Snowden is hoping for a similar first-up showing in Saturday's feature.

"Judging on the way he's spelled and come back this time in, it's definitely the best I've had him," Snowden said.

The import won the Newcastle Cup last spring and that race, along with the Group One Metropolitan, is on his spring radar.

Two-time Group One winner Pride Of Dubai is also progressing well and remains on target to trial at Randwick on August 17.
