In Secret had her first race start at Scone Racecourse on the 14 May 2022 in the Woodlands Stakes. She won the race comfortably when ridden by Hugh Bowman, who stated after the race, "She has got a bit of a class edge on this lot, and she is certainly up to better things."^[3]

In Secret then ran second in the Golden Rose Stakes before winning the Group 1 Coolmore Stud Stakes at Flemington Racecourse when ridden by James McDonald.^[4]
