Guaranteed Secret, a two-year-old filly by Guaranteed and one of the first crop of the former Grand Circuit star, turned in a bold front-running display to post her first success at Maryborough on Thursday (November 18).

She is the third winner sired by Guaranteed from nine starters so far.

Guaranteed Secret clocked quarters of 28.2, 29.7, 28.8 and 28.6 on her way to a 5.2 metres win.

The mile rate for the 1690 metres was a slick 1:55.1.

Bred and raced by Sue-Ellen Thompson, Guaranteed Secret is out the Barnett Hanover mare Secret Bonus, who has left six winners from seven foals of racing age including Presidentialsecret (1:51.1).
