La Collina is a chestnut mare with a narrow white blaze bred in Ireland by the County Limerick-based Manister House Stud.
[3] La Collina's dam Starfish never ran in a race but was a great-granddaughter of the Irish mare Sorbus whose other descendants have included Oasis Dream, Zenda and Kingman.
[5] In the following month the filly was stepped up sharply in class to contest the Group 3 Silver Flash Stakes over the same distance at Leopardstown Racecourse.
Starting at odds of 10/1 in a six-runner field she made steady progress in the straight but failed by a neck to overhaul the Aidan O'Brien-trained favourite Maybe.
On 7 August at the Curragh La Collina was matched against male opponents in the Group 1 Phoenix Stakes over six furlongs and started a 33/1 outsider.
On her three-year-old debut La Collina was sent to England to contest the 1000 Guineas over the Rowley mile at Newmarket Racecourse on 6 May and finished fifth behind Homecoming Queen, Starscope, Maybe and The Fugue.
[9] On her first run as a four-year-old La Collina was beaten only half a length when finishing third to the colts Custom Cut and Nephrite in the Group 3 Gladness Stakes at the Curragh on 7 April.
La Collina raced towards the rear of the field but made steady progress in the last quarter mile and was in fourth place when Hayes switched her to the outside approaching the final furlong.
The filly produced a strong late run, gained the advantage in the final strides, and won by half a length and a short head from Lily's Angel and Say.
"[12] On her final racecourse appearance, La Collina ran for the second time in the Sun Chariot Stakes and finished fifth behind Sky Lantern.
