Court Up In Rio's pedigree suggested he would handle the heavy going, and it was proven at Thoroughbred Park on Friday when he took out the Class 1 Handicap (2000 metres).
The sire and dam of Court Up In Rio both descend from areas of the world where wet tracks are common, and Friday's surface at Canberra was rated at a heavy-10.
Knowing his ancestors were bred to handle wet tracks gave trainer, Gary Colvin assurance that his galloper would be a contender on Friday.
"We were quietly confident," the Wagga Wagga based trainer said.
"He's by an Irish stallion and out of a Great Britain mare, so I reckon he wouldn't mind the sting out of the track."
Court Up In Rio scored his maiden win at the fourth time of asking two starts back when Colvin stretched his galloper out from the 1400 metres to the 1800 metres.
Colvin extended the Estambul gelding out even further at Canberra on Friday, with his win over the 2000 metres further stamping him as a stayer to keep an eye on.
"Once we've gotten him over a bit of ground, we've started to get some benefit out of him," Colvin said.
"We brought him out to the 1800 (metres) and he won, and we've upped him again to the 2000 (metres) and he's done it again."
Court Up In Rio's retired half-brother, Rambert was also a staying type. Rambert scored all six of his career wins over 2000 metres and up.
Rambert's career highlight came in a 2500-metre race at Moonee Valley early last year, and Colvin is excited about his own galloper's prospects.
Patrick Murphy rated Court Up In Rio for his latest win, and only picked up the ride on Friday morning after the initially-engaged hoop, John Kissick, pulled out of the Canberra meeting due to illness.
It was Murphy's first ride aboard Court Up In Rio and it was enough to show him that the four-year-old is a genuine staying type.
"I've ridden winners for Gary (Colvin) before, so I've had an association with him, but I haven't ridden a winner for Gary in a while so it was good to get that one for him," Murphy said.
"(Court Up In Rio's) pretty one dimensional. He just has no turn of foot, but he loves the distance, and loves the wet track.
"He just kept fighting along, and I was waiting for someone to come up to him because he was just going that one speed, but he fought them off and won quite convincingly in the end."
