Treasurethe Moment is set to step out for her first run as a four-year-old in a Group 1 contest at Caulfield.

Trainer Matt Laurie is aware of the task confronting Treasurethe Moment when she makes her seasonal debut in the Memsie Stakes at Caulfield. 

The nine-time winner from 11 starts will tackle the older horses for the first time in the Group 1 contest over 1400m on Saturday. 

Treasurethe Moment has strung together eight wins in succession, including four during an autumn campaign that saw her restricted to fillies' company. 

But Laurie took heart from watching Aeliana, also now a four-year-old mare, give Via Sistina a scare in the Group 1 Winx Stakes (1400m) at Randwick last Saturday. 

"We feel she's come back really well," Laurie said. 

"She's here and she's ready, but I'm still mindful that she is not four until November, so she's very much racing as a three-year-old filly. 

"It's bit more of a challenge for her to prove it again against older stock, but she's a wonderful horse and it would be hard to see her not picking up something along the way. 

"She's shown nothing but class and I think we can assume she's going to measure up, whether that's over the seven (furlongs, 1400m) we'll find out, but certainly over a bit of ground. 

"She's had two big, solid preparations getting out over some good ground, but she's sharp and she's keen and enjoying her work and we're really looking forward for what is ahead." 

Of concern for Laurie is the prospects of a wet track. 

The Melbourne Bureau of Meteorology is forecasting anything from 6-to-30mm of rain, with the potential of 8mm on Saturday. 

"I think she's a lot happier on top of the ground," Laurie said. 

"She's got that skimming action and can quicken up really well, whereas a softer surface can take that away from a horse. 

"You can't control the weather, so we'll have to kick off." 

Laurie has mapped out a program to take in the Makybe Diva Stakes (1600m) at Flemington on September 13 and the Turnbull Stakes (2000m) in October before a decision is made on whether to head to the Cox Plate (2040m) at Moonee Valley or the Caulfield Cup (2400m). 

While Treasurethe Moment was a dual Oaks winning filly at 2400m and 2500m, he is still unsure what her best trip will be. 

"She was a stayer as a three-year-old and could win over seven (furlongs, 1400m)," Laurie said. 

"I would be very excited to tackle an eight-furlong (1600m) race at Flemington. It's a beautiful track for her the way she likes to gallop, and she can get ten (2000m). 

"All that remains to be seen is what her pet distance is. The beauty of her is we can front up to a variety of different ranges and be competitive." 

A field of 11 has accepted for the first Group 1 of the Melbourne Spring Carnival with Treasurethe Moment drawing in barrier one under Damian Lane. 

Chris Waller has Fangirl (5) and Buckaroo (7) among acceptances while Ciaron Maher will saddle up Another Wil (3) and Zardozi (10).
