Winx has drawn barrier five of 11 in the race named in her honour at Randwick as she tries to set an Australian record of 26 consecutive wins.
Godolphin horse Kementari, viewed as her main opposition, will jump from barrier seven in Saturday's 1400m-Group One race.
Kementari was a late addition to the Winx Stakes on Tuesday and introduced into the TAB's market at $8, the only other runner under double figures with Winx at $1.10.
