A gear change and a rise in distance are both expected to benefit three-year-old Glenn Road when she makes her city debut at Flemington.

And while trainer Henry Dwyer would prefer some rain in the lead-up to Saturday's National Hall of Fame Handicap (1200m), he believes the filly has the talent to measure up in the city race.

Glenn Road is one of about 15 former Peter Moody-trained horses which joined Dwyer's team after Moody was suspended for six months in March and subsequently closed his training business.

Five-year-old mare Dig A Pony, who is set to have her first start for Dwyer on Saturday, is another.

Dwyer's expansion has also included taking over 18 boxes which were allocated to Moody at Caulfield.

A Tatura maiden winner at her second start in March, Glenn Road made her debut for Dwyer when running home for third over 1000m at Ballarat on May 8.

Dwyer has added winkers which he believes will help the filly focus more.

"And I think the step up to 1200 metres is going to be right up her alley," Dwyer said.

"We sent her in pretty underdone at Ballarat and she's improved off that run significantly, so I think she should be a chance."

Dwyer said Glenn Road was not the easiest horse to train because of her attitude, and a few little soundness issues.

"But she's got ability there, so you don't mind persevering," he said.
