Begg said Saturday's Makybe Diva kick-off best suits She's A Hustler's program towards the Caulfield Cup.
After Saturday it will be the Turnbull Stakes (2000m) at Flemington on October 3 then two weeks later the Caulfield Cup.
"It's such a tight turnaround after winter," Begg said.
"The right race for her is probably the Underwood over 1800 metres, but it's only two weeks, two weeks (to the Caulfield Cup).
"Going that way, you don't get to have a three-week buffer.
"It's a very tight schedule, unless you started early in something like the Heatherlie, but she looks to be tracking nicely.
"She's got good residual fitness from Brisbane and having that has allowed us to kick off here as she raced right up until the middle of June and then she was able to have a bit of a break up there."
She's A Hustler has had two trials at Caulfield Heath to prepare for Saturday's return, winning her latest over 1400m.
"She took enormous improvement from her first trial to her second," Begg said.
"And her coat is really starting to move now."
