On her track debut she started at odds of 7/2 for a maiden race over seven furlongs at Leopardstown Racecourse on 11 July and finished third of the seven runners behind Love and Soul Search under a gentle ride from Foley.

[4] On 2 August the filly started 7/4 favourite for a similar event over the same distance at Galway and won "comfortably" by three and a quarter lengths from the Aidan O'Brien-trained Santiago after taking the lead a furlong from the finish.

[5] Three weeks after her win at Galway Alpine Star was stepped up in class to contest the Group 2 Debutante Stakes at the Curragh and started the 2/1 second choice in the betting behind Love in a nine-runner field which also included Soul Search.

After tracking the leaders, Alpine Star made steady progress in the last quarter mile and overhauled Love in the final strides to win by a short head.

"[7] The filly was expected to end her season with a trip to France for the Group 1 Prix Marcel Boussac at Longchamp Racecourse in October but was pulled out of the race after sustaining a muscle injury.

[11] On 5 July Alpine Star was sent to France to contest the Prix de Diane over 2000 metres at Chantilly Racecourse in which she was ridden by Stéphane Pasquier and went off the 2.1/1 favourite in an eleven-runner field.
