"The mile distance is his go. I think if he can get a nice draw, in an ideal world it would be [barrier] 5, 6 or 7, and if that happened we'd be over the moon. We're just very pleased and honoured to have a horse good enough to be in the race."
Hiflyer had a brief campaign in Sydney over winter and Lock believes that trip has been the making of the gelding heading into his spring preparation.
"I think he has improved a tonne," Lock said. "He has really grown up. Unfortunately we only had the 1400m and 1500m [starts], I think if we had seen him run in a mile over there we would have probably seen him win a race.
"It was a learning curve. It's his first trip he has been away, so we decided to give him two runs, we made that plan before we left.
"He did the two runs and came through them extremely well. He came home to compete against New Zealand's best sprinters over 1400m, which is a hard task to do coming back from Australia and he did it pretty well. We are more than happy with the way things have turned out and it would be a fairytale if he can win on Saturday."
All going to plan Lock will give Hiflyer the chance to test himself over 2000m in his remaining two spring targets, the group one Livamol Classic (2040m) at Hastings on October 6 and the group one Emirates Stakes (2000m) at Flemington on the last day of the Melbourne Cup Carnival.
"He's had one run over 2000m in the Zabeel Classic and that didn't pan out our way," Lock said. "It was a wet track and the back runners never ran on at all.
"I think we would be silly not to try him over 2000m and if it doesn't work we know to go back over the mile. We know he is very competitive over that distance.
"If it all comes together our big plan is to target the Emirates on the last day of the Melbourne Cup carnival. It's worth A$2million and a nice slice of that would be very handy."
