And the hard-working hoop hopes it will open the door to more opportunities.

The three-kilogram claiming apprentice pushed Run Like A Rebel ($9) to a short half-head win over Eurosay ($21) in a Highway Handicap for Braidwood trainer Aaron Clarke.

It was Weir's third Highway race win but her first city victory in about a year.

"It's just hard to come by, the opportunity in town," Weir said.

"Being a female always is hard because they just preference the male apprentices over the female apprentices."

The success followed a career-best day for Weir at Moree three weeks ago.

"It has been a really good month, after riding four winners at Moree, that was probably my biggest achievement so far for one day," she said.

"I hadn't ridden three winners in a day before."

Weir, a national champion rodeo rider with 10 years experience before turning to racing, came to the Hunter in 2015 from Kembla with her partner and became an apprentice to Todd Howlett.

The Lower Belford trainer was thrilled to see Weir grab another city win.

"She's a really good horsewoman and she works hard," Howlett said.

"She does a lot of travelling, she's got her own property and horses and she's a real goer. She's always doing something."

AAP report on Saturday: Trainer Aaron Clarke was unsure if he would make it to Rosehill after an anxious night guarding his Braidwood stables from a bushfire threat.

But thanks to a timely wind change, his stables were spared and Clarke was able find safe passage through the bush fire zone to travel to Sydney on Saturday with Run Like A Rebel.

The horse then delivered the perfect tonic with a Highway Handicap (1200m) win.

"We were worried about getting through but we were pretty lucky and I know most of the blokes that work down there so we got through," Clarke said.

"I was sitting in the stables until about twelve o'clock and then getting up this morning but anyway, we got here.

"The fire only got about a kilometre from the stable. It was pretty hairy.

"It nearly jumped back but the wind just changed and it helped us out a lot."

Run Like A Rebel ($9) gave Clarke his first Highway Handicap win and first city victory since Romance Can Costa scored at Canterbury in July last year.

Ridden by apprentice Mikayla Weir, the mare held on by a short half-head over Eurosay ($21) with top weight Greenspan ($51) another 1-1/2 lengths away.

Clarke said his luck was starting to turn after a quiet period for the stable.

"We had a good crew a few years ago and had some nice horses but then we went through a rough patch with not many," Clarke said.

"We're just starting to get a few nice ones and have a bit of luck."

The Highway Handicap was split into two divisions on Saturday to cater for the large number of nominations.

The other edition was won by the Mitchell Beer-trained favourite Princess Cordelia, who showed her rivals a clean pair of heels under Tim Clark.
