The following spring, Harayir became the first horse to win a Classic on a Sunday, when she was victorious in the 1000 Guineas at Newmarket Racecourse after being rejected by her regular jockey Willie Carson in favour of her owner's other runner Aqaarid.

Harayir was a bay filly with white socks on her hind legs,[1] bred in Kentucky by her owner, Hamdan Al Maktoum's Shadwell Farm.

At Newmarket's July meeting, Harayir was moved up in class to Group Three level to contest the six furlong Cherry Hinton Stakes.

Willie Carson sent the filly into the lead a furlong and a half from the finish but she was caught in the last stride and beaten a short head by Red Carnival.

[7] On her final appearance of the year, Harayir started favourite for the Group One Cheveley Park Stakes at Newmarket, and finished third to Gay Gallanta and Tanami.

Harayir's three-year-old debut saw her matched against colts as she carried top weight of 133 pounds in the European Free Handicap in April.

[12] Harayir started favourite for her rematch with Ridgewood Pearl in the Coronation Stakes at Royal Ascot where she was expected to be better suited by the firm ground.

In the Falmouth Stakes at Newmarket Harayir suffered a third consecutive defeat after thunderstorms the day before the race softened her preferred firm ground.

[16] Fifteen days later, Harayir added a second success in mixed company, beating the colt Darnay by half a length in the Group Two Celebration Mile at Goodwood.

In September Harayir moved down to sprint distances for the first time since her two-year-old days and finished fourth to Cool Jazz in the Diadem Stakes at Newmarket.

She started favourite against a field which included Red Carnival and Cool Jazz, as well as the Lockinge Stakes winner Soviet Line.
