The Dubbo businessman is a part owner in the Chris Waller trained Libran and one of the pre-race Cup favourites, Humidor.

Libran ran well to finish eighth, while Humidor battled over the course of the two mile distance to run 19^th, well back from where both Walker and jockey Blake Shinn expected the five-year-old to fare in the $6.2 million race that stops the nation.

At Flemington with family and friends to be part of the cup day festivities, Walker said being present for the most prestigious race in the country was an incredible experience on its own.

Having two runners in the field, that just made it all the more memorable.

“Firstly I’ll say, for me it was an exciting day,” Walker said.

“It was a privilege to have two runners in the cup, to be honest. 

“I was certainly nervous before, I was pretty good up until the race before (the Melbourne Cup) and then it started to sink in.

“You see the other owners, trainers, you’re among those people and it really is a privilege.

“I was very proud of the horses. Humidor tries his heart out but the jockey did the right thing by letting him canter to the line.

“I had family and friends with me … it was a day to remember. You get into the mounting yard and it was just a great experience. It’s an iconic race.”

Walker said he was immensely proud of Dwyane Dunn’s ride on Libran, the seven-year-old $61 outsider one of only two Australian trained horses to finish inside the top 10.

While after finishing second in the 2040m Cox Plate and winning the 1600m Makybe Diva Stakes, Humidor failed to stay the 3200m distance of the Melbourne Cup.

“He just doesn’t run two miles (3200m), it’s as simple as that,” jockey Blake Shinn said post race.

Walker agreed.

“It just didn’t suit him. It was a slowly run Melbourne Cup and they weren’t making up the ground from where he was,” he added.

“He didn’t stay the distance. He’ll go to the paddock and we’ll aim for the Australian Cup again which he won.”

The Australian Cup is run over 2000m, and Walker said Humidor will be angled at races of similar distance in the future.

But the search for a Melbourne Cup winner continues for Walker: “I’l be on the look out,” he added.

Libran will be targeted at the Sydney Cup, and based on his run on Tuesday Walker believes he’ll be an early favourite for that race.
