Along with the Straight Six at Flemington, the Randwick Mile holds a distinctive place in Australian racing.

The scene of the flagship Doncaster and Epsom Handicaps, it is regarded as the toughest 1600 metres in the country and a test of both endurance and speed.

Gai Waterhouse has made an art form of winning Doncasters and Epsoms and Chris Waller is keen to build on his own record of victories over the course including Saturday's Group Two Villiers Stakes in which he has two runners - Snow Alert and Altered Boy.

Waller has won two Doncasters with Triple Honour in 2008 and Rangirangdoo earlier this year.

He also won a Villiers when Honor In War got the race on protest from Takeover Target in January 2008 when it was reduced to 1400 metres as racing returned from the equine influenza outbreak.

"The Randwick mile is special," Waller said.

"It's the classic distance, sprinters and stayers have an equal opportunity.

"If you win one you get attached to it.

"I've made a handful of public speaking engagements and I found myself getting quite emotional over the Doncaster."

Snow Alert is the Villiers topweight with 58 kilograms with Altered Boy joined on 57.5 by Canberra Cup winner Macknuckle.

"The weight is certainly a concern and they are both up against it," Waller said.

"But they are both good horses in pretty good form."

Waller would also have preferred better barrier draws for his pair with Snow Alert in 12 and Altered Boy nine.

Snow Alert ran second to Stratofortress, who was scratched from the Villiers on Friday through injury, in the Newcastle Cup (2300m) in September.

He will be having his first start since his seventh in the Emirates Stakes on the last day of the Melbourne Cup carnival at Flemington.

Waller decided to freshen him up for the Villiers rather than give him a spell and get him ready for the Doncaster.

"I don't really think he is a Doncaster type of horse and we're looking at a race like the Doomben Cup as a Group One target next year," he said.

Altered Boy is on a seven-day back-up after returning to winning form at Rosehill last Saturday.

Triple Honour, who gave Waller his first Group One victory when he took out the Doncaster, runs in Perth on Saturday.

He will line up in the Group Two CB Cox Stakes (2100m) after an encouraging sixth in the Group One Kingston Town Stakes (1800m) last Saturday week won by three-year-old Playing God.

"It was an improved run last time and he may stay there for the Perth Cup," Waller said.

Triple Honour will be ridden by Willie Pike replacing the suspended Damien Oliver.
