1983: two-year-old season

Gala Event began her racing career with a win over six furlongs on good to firm ground at Navan Racecourse in June. Later that month, over the same course and distance, faced eight rivals in the valuable Woodford Stakes and reportedly "cantered" to victory by three lengths. In August the filly was stepped up in class to contest the Group 1 Phoenix Stakes at Phoenix Park Racecourse and was made the 2/1 favourite. After disputing the lead for most of the way she was overtaken in the final strides and finished third behind the colt King Persian and the filly Grey Dream. It was reported that she had lost a shoe during the race. A week after her defeat in the Phoenix, she started odds-on favourite for the Group 3 Anglesey Stakes at the Curragh and won "comfortably" by one and half lengths from Late Sally after taking the lead soon after the start.^[3]

On 10 September Gala Event was one of twenty juvenile fillies to contest the Moyglare Stud Stakes over six furlongs at the Curragh and was made the 9/2 second favourite behind the British-trained Desirable (winner of the Princess Margaret Stakes). The other fancied runners included Ballet de France, Ispahan, Shindella (third in the Windsor Castle Stakes) and Bold Meadows. Ridden by Kevin Moses she tracked the front-running Welsh Woman before taking the lead on the outside approaching the final furlong. She held off the challenge of Deirable to win by three quarters of a length with Welsh Woman hanging on to take third place.^[3] On her final race the season the filly was sent to England for the Cheveley Park Stakes at Newmarket Racecourse. Ted Curtin had sent out Gentle Thoughts to take the race in 1973 but had not trained a winner in Britain since. Starting the 6/1 second favourite she was in contention for most of the way before being outpaced in the closing stages and finished fourth behind Desirable, Pebbles and the favourite Prickle, beaten just over a length by the winner.

In the official Irish Free Handicap for the two-year-olds of 1983, Gala Event the rated the best filly, albeit fourteen pounds inferior to the top colt El Gran Senor. The independent Timeform organisation gave her a rating of 112, nine pounds behind the French-trained Treizieme who was their best juvenile filly of the season.^[3]

1984: three-year-old season

Gala Event missed most of her second season through injury and made only one appearance on the racecourse. In September she contested the Barronstown Stud Stakes over seven furlongs at Phoenix Park in which she finished sixth of the eight runners in a race won by the three-year-old colt Red Russell. At the end of the season she was given a rating of 98 by Timeform.^[2]

1985 & 1986: North American racing career

For the 1985 season, Gala Event was transferred to the United States where she was trained by John Sullivan in California. She made a successful North American debut when she won the Splendid Girl Stakes at Hollywood Park Racetrack on 22 June. She failed to win again that year, with the best of her six subsequent efforts coming when she finished third to Capichi in the Grade II Palomar Handicap.^[5]

Gala Event remained in training as a five-year-old but after being beaten in two allowance races at Santa Anita Park in January she did not run again.^[5]
