Gammalite's trainer was Leo O'Connor and his regular driver was Bruce Clarke, who drove him to 65 wins.

Gammalite was unplaced in two of his first three two-year-old race starts, before recording ten successive wins including the Victoria Breeders Plate and the Edgar Tatlow Memorial Stakes both at Moonee Valley.

[4] He now had accumulated 48 successive race wins or placings before finishing fourth at Harold Park and had taken his lifetime earnings to $307,008.

[2] Gammalite had two wins and three seconds in the 1981/82 season before he was taken across the Tasman Sea for racing at the New Zealand Cup meetings.

In the cup five-year-old Gammalite fought on courageously to defeat Bonnie's Chance by a head in 3:24.6, a national record for a stallion for mobile start over 2,700 metres, but not equalling Delightful Lady's 3:22.9 of the previous year.

At six years old during the 1982/83 season Gammalite had eight starts at Moonee Valley, Bankstown and Harold Park for one win and three placings.

After Gammalite's win in the G1 Cranbourne Cup on 28 February 1983 he was flown to Auckland for his first attempt at the Inter Dominion Pacing Championship.

Popular Alm, who had won ten of his eleven clashes with Gammalite, was an Inter Dominion Grand Final contestant, too.

[2] Gammalite had a further 24 race starts during the 1984/85 season which included wins at Bankstown, Tweed Heads, and the Gold Coast.

[2] Gammalite won most of the mainland Grand Circuit and Group races except the Miracle Mile Pace.

[9][11] In 2009 he was elected to the Victorian Harness Racing Media Association Hall of Fame in its first year of operation along with his great rival Popular Alm.
