A "relaxed" workout was all champion mare Winx needed to complete her preparation for Saturday's Group I Turnbull Stakes (2000m) at Flemington.
Winx's work on the steeple grass on Thursday was more leisurely than her quick gallop on the Flemington course proper earlier in the week but equally pleased Waller two days before the five-year-old's final Cox Plate lead-up.
"Her work has been good, highlighted on Monday morning by a sharp piece of work," Waller said.
"Therefore, this morning, she didn't need to do a lot and she had a pretty relaxed workout and three-quarter pace.
"(Jockey) Hugh (Bowman) was happy, I was happy. I couldn't change anything."
Winx is one of seven runners in the Turnbull Stakes but bookies only give the Makybe Diva Stakes winner Humidor a serious hope of ending the great mare's 20-race winning streak.
Bowman said the Darren Weir-trained Humidor could provide Winx with her toughest challenge of the spring.
"I have got a very healthy respect for Humidor," Bowman said.
"I thought his win last start was very impressive and he beat a class field and, with due respect to Happy Clapper, I'd say he's the toughest opposition that she's met this preparation.
"Obviously there is a long tail to the depth of the field but I won't look too much into that.
"I'll do what I always do and give her every chance to do what she can do."
Waller said he hadn't had a deep look at the Turnbull Stakes field but was confident Winx would meet any challenge the small field provided.
"To tell the truth, I haven't looked at it (the Turnbull Stakes field)," Waller said.
"I know Humidor is in the race. Team Williams have got a few runners but apart from that, I haven't taken too much notice.
"The beauty of Winx is that she can adapt to all situations, be it a big field or a three-horse field, a handicap, weight-for-age and set weights and penalties and track conditions are the same.
"We won't over analyse things."
