All eyes are on the weather for this Sunday's Three Rivers Machinery Narromine Gold Cup.

"We have had good rain so it's a heavy 7 so far for Cup day, but the track is holding up," says Narromine Turf Club secretary Tristan Penson.

Nine races are on the card, with the $40,000 Cup feature race attracting a strong field.

Scone trainer Brett Cavanough is bringing his in-form gelding Indifference and Ms Penson believes he will be one of the favourites with punters.

''He has in-form Braith Nock, reigning country apprentice of the year, aboard so is a strong chance,'' she said.

Amongst the other Cup contenders, Star Dubbo trainer Clint Lundholm has 5-year-old Slush Fund,that has won 2 of last 3 starts and is placed at the track.

And there's little doubt Mudgee trainer David Smith also has a major claim with Lockdown Gamble.

''He likes 1600m and was not far away in the Dubbo Cup prelude,'' said Ms Penson.

Another Scone trainer, Cameron Crocket, has entered six-year-old gelding Rajnish, which loves the distance winning 4 from 10.

As with all country races, it's not all about what's happening on the track from mid-day.

''A garden party, fantastic fashions on the field, fun music entertainment and Wiradjuri Rabs - known on social media for his crazy race calls - will add to the flavour,'' said Ms Penson.

She suggests race fans keep an eye for the computer-based Fashion Glam Bot.

''The owners of the technology are trying it out on Cup Day. It takes videos and pictures of fans without them knowing, so it will add to the fun of the day,'' she said.

Saturday night's Calcutta at the Narromine United Services Club is expected to be popular, with star trainer Clint Lundholm and jockey Zoe Hunt as guest speakers.
