The first aircraft was written off during trials, however, and as there were no other competitors, the American Aero Club postponed the competition to 1925.

The aircraft was fitted with Lamblin radiators on the leading edge of the lower wings.

[2] With a 20 ft (6.1 m) wingspan, the Gloster was the smallest British aircraft ever built with that power at that time.

When the race took place, the Gloster III was outclassed by the Curtiss R3Cs of the United States, with the race being won by Lieutenant James Doolittle, flying a Curtiss R3C at an average speed of 232.573 mph (374.443 km/h),[7] 33 mph (53 km/h) faster than Broad, who recorded a speed of 199.091 mph (320.537 km/h),[8] with De Briganti in the Macchi M.33 finishing third and the remaining two Curtiss R3Cs failing to finish.

After modification, they were used for training pilots of the RAFs High Speed Flight in preparation for the 1927 race.
