Terry Robinson etched his name into the racing records books on Saturday, becoming the first-ever trainer to claim the Country Championship/Kosciuszko double at Royal Randwick.
In the fourth edition of the $1.3 million dollar 1200-metre race, the Regal Lodge gelding, ridden by Tommy Berry, made his move in the final stages, to pip former winner Handle The Truth for line honours.
"This is easily one of the finest moments of my career - it's just a wonderful feeling to be here," Robinson told Sky Racing.
"I never thought I would train a horse like him, but for my family, this is just an amazing story.
"He is a 1400m [horse] and we saw that at the end. I thought he was going to be strong and he was."
Speaking to Robinson's selfless nature, he was quick to share the recognition around to long-standing Mick Lill, his family, staff and jockey Berry
"It is a wonderful feeling to be here. He is just a super horse," Robinson said.
"For Mick, you must have the greatest smile on your face.
"He has been a trainer, he bred this horse and it is a great result for him, my staff and my family.
"I always thought his best distance is yet to come when he gets up to 1400, 1600.
"What Tommy, who's a good friend of mine, and Arty have been able to do this year makes me so proud."
Berry also heaped praise on the five-year-old, saying he just continues to rise to the challenge when called upon - proving why Art Cadeau has to now be considered the state's premier country galloper.
"He had a little bit of work to do at the top of the straight, but as I said all week, we just don't know how good he is yet, because every time we raise the bar, he keeps jumping it," 30-year-old Berry said.
"He loves to get in a bit of a battle there and he beat one of those hard heads that have been running in Group races all his campaign (Handle The Truth)."
Despite numerous punters having fears the distance might not suit Art Cadeau, especially after a 24-week spell, Berry knew Robinson's impeccable training regime would have him ready for race day.
"I spoke to Terry Friday morning, and it was the first time I had spoken to him leading into a race with this horse where he said, 'I couldn't have him any better',' Berry said.
"I was pretty confident after that.
"He felt strong all the way through... He has had that perfect preparation all the way through, where it was the complete opposite of last preparation.
"I think Terrys' training performance to get him to the championships was good but he's a tough horse.
"A lot of people were querying whether Terry could do it with him first up, but he knows this bloke back to front."
