Hit The Sky will be the first horse he starts from his new West Melton stable.
Barron spent the past two seasons in a successful training partnership with his brother, Ken.
The pair trained 90 winners together before mutually agreeing to part ways before the end of last season.
Hit The Sky could get Barron’s new venture off to a good start in race 3, a 2700m handicap.
The horse will need to do little more than he did in a recent Rangiora trial. Hit The Sky was only one-and-three-quarter lengths behind star filly Princess Tiffany in the 2000m hit-out.
"I would be disappointed if he wasn’t in the top three. He is a great standing-start horse and a great-gaited wee fella," Barron said.
"He seems to have come up very well — he is definitely stronger. I am very happy with him."
Hit The Sky will meet a small field of race-hardened horses in tomorrow’s feature pace.
Donegal Carrickfin looks to be Hit The Sky’s main rival following his solid third at Oamaru last weekend.
The horse put in a good effort to place after beginning slowly and losing momentum on the home turn when locking wheels.
Bettor Sensation is unbeaten in two standing starts and is another serious player in race 3. He comes in to the race fresh after last running at Forbury Park in mid-June.
The placegetters in last weekend’s feature trot at Oamaru should feature at Forbury Park tomorrow night.
Winner Trick Star, second placegetter Dusky Eyre and fourth-placed Pyramid Magic start in race 7.
Both Dusky Eyre and Pyramid Magic get a 10m advantage in the handicaps over Trick Star compared with the marks they started from last weekend.
That could be enough for the revitalised Dusky Eyre and his driver, Blair Orange, to get a head start on their main rivals and control the race in front.
Madison Jane and Kiwi Crusher are serious contenders for the race despite coming off last-start failures.
Motu Top Mach, Omar Sharif and Mr Midnight are set for an epic clash in race 5.
Omar Sharif has revitalised his career with two wins in his last three starts at Forbury Park.
Mr Midnight has also been going strong races and was just nosed out by Clive at Oamaru last weekend.
Motu Top Mach showed he had plenty of talent late last season and returns to the track for the first time since June.
