Sydney owners Emilio and Mary Rosati banked the winner's share of the $60,000 feature's purse when their Phil Williamson-trained trotter produced a strong front-running performance.
Driver Nathan Williamson pushed the former $160,000 blue-blooded yearling from barrier 5 to the front; from there the pair never gave their rivals a look in.
Getting a front line draw for the first time in his career meant Ultimate Stride could show his class, Phil Williamson said.
"That was the first time he had drawn the front row. He put a bit of a statement out there tonight.
"He is a lovely trotter, but he has still got a bit to learn.
"He will come back for the Sires Stakes race next week and hopefully he can get a decent draw again."
A father-and-son one-two looked likely in the home straight until the Brad Williamson-trained Cracker Hill galloped about 50m from the finish.
Midnight Dash ran past him to take second placing.
Cracker Hill was third at the finish, but relegated to ninth.
Later last night, Belle Of Montana produced a stunning win in the group 1 Nevele R Stud Fillies Series Final.
The Barry Purdon-trained 3yr-old came off a hot speed with a sizzling finish to run straight past the favourite and her main rival, Princess Tiffany.
Driver Zachary Butcher was left searching for superlatives to describe Belle Of Montana after their win in the $140,000 feature.
"The way she rounded them up was pretty awesome," he said in his post-race interview.
"She is as quick as any horse I have driven."
Belle Of Montana and Ultimate Stride both registered New Zealand records in the recently established 1980m distance.
