Jeff Allis has inked multimillion dollar business deals throughout his career, but says nothing compares to the thrill of winning a horse race.

The Boost Juice founder tasted success with Tiger Shark in the $125,000 QTIS 3YO Plate (1200m) at Doomben on Saturday and has a smart filly on his hands.

Allis, along with wife Janine invest in businesses through her role on popular TV show Shark Tank, but Allis said the $12,000 he spent on Tiger Shark as a weanling is up there with the best money he has spent.

The power couple now call Noosa home, with McCall training a handful of horses on the Sunshine Coast for them.

“Racing is the most exciting thing for sure, nothing compares,” Allis said post race.

“If you’re not part of it, it’s hard to understand, but standing there today was sensational and the prizemoney pays a few bills.

“We just invest in businesses, Janine got a heap of them on Shark Tank back in the day, so we have those and race horses.”

Allis owned Group 2 Matriarch winner Jessy Belle, but said he is happy with a smaller team of horses based in Queensland now.

“We have probably had about a hundred in our time, we used to have a farm, but not anymore,” he said.

We were down in Melbourne and got involved around 2008.

“We have a place up here, we have found a good trainer in Nat, we love her communication and getting winners like this really helps.

“It’s all about getting a trainer you trust, we trust her completely, we have some weanlings together – we got this one as a weanling for $12,000.

“When we had the farm, I used to love the babies, so we have more weanlings this year on Nat’s farm.”

McCall said she may look at options down south following the impressive wire-to-wire win, where jockey Damien Thornton kicked off the Doomben turn, beating home race favourite Deep Respect and Spin Doctor.

“We were very confident she would improve after last start, she is a big, gross filly, so always going to be better second up,” she said.

Meanwhile, trainer Kelly Schweida showed breeding doesn’t count for much once they are on the track as home-bred hero Vodka Martini took his record to seven wins in 10 starts.

The four-year-old has been sent out a hot odds-on favourite in his last three starts, and is yet to disappoint, winning all three.

Saturday’s effort in the Benchmark 78 Handicap (1200m) was arguably his best, reeling in tearaway leader Coco Rox in the dying stages after a tough run in transit.
