The in-form trainer will make the five-hour trip a day earlier, before settling in overnight in a bid to give their gallopers the best chance at Forbes Jockey Club's inaugural showcase meeting.

She admitted that she didn't know whether all her charges would handle the five-hour long trip and change in stables - they'll be housed with Dennis Bush - but she was confident going up the day before would give them the best chance.

Jarvis will boast a two-pronged attack in the feature event, with Airfree and Napoleon Solo contesting the $50,000 Forbes Cup. The latter is a former Peter and Paul Snowden galloper and appears the best chance in the 1600m race.

"Napoleon Solo has only had the one start for us on a very heavy track at Goulburn and that didn't suit him." Jarvis said.

"His form for the Snowden stable is excellent and we bought him as a country cup horse, and he will go to Forbes then will we look at races like the Moruya Cup and Bega Cup."

The winner of three races from 31 starts has won nearly $300,000 in prizemoney and based on his fast-finishing second place at Rosehill over the 1400m back in May, the five-year-old looks as though he will be a major player come Sunday.

Jarvis will also have her mare Airfree running, with the six-year-old being given one more chance at the races after finishing a nice third in the Tuross Cup at Moruya last start.

Napoleon Solo, to be ridden by Jordan Mallyon, was a $23 chance on Friday while the Kayla Nisbet-ridden Airfree was at $51.

Wild Rocket was a $4 favourite for Narromine trainer Kylie Kennedy while Brett Cavanough's Eiger, the Laura McCullum-trained Necessary, and From The Bush of the Bathurst stables of Gayna Williams were all $5.

Reward Seeker was at $7 for Wellington's Michael Mulholland while Dubbo hope Toulon Brook, trained by Kody Nestor, was at $14.

Reward Seeker, winner of the Wellington Cup last preparation, ran fourth first-up at Narromine last week but tuned up for the Forbes feature with a Cowra trial win on Tuesday.

Toulon Brook won at Dubbo tow starts back but finished 10^th last time out at Tamworth.

Nestor also has Sizzling Star and Super Chance racing on Sunday.

The cup jumps at 3pm.
