Born in Toronto, Ryall was sent to England to be educated in 1900. In England, he began working as a general reporter for the newspaper London Exchange-Telegraph and began writing racing reports from England for New York World.
Ryall afterwards went to New York City, and his first column for The New Yorker was published on July 10, 1926. The New Yorker had been launched on February 21, 1925. Ryall chose a pen name because at the time he was still writing for New York World; he used this name in honor of Audax, the nom de plume of British racing journalist Arthur Fitzhardinge Berkeley Portman. (Ryall's full name was George Francis Trafford Ryall. His son, a horse-racing photographer, and grandson, an art photographer, both received the same name, designated as generations II and III.)
He was the writer of longest record in the history of the magazine, and his column, “The Race Track,” ran from 1926 to 1978. He wrote on various aspects of horse racing, from starting barriers to horse training, from the Saratoga Special Stakes to the names given horses. "Being one of those peevish fellows who believe that every horse deserves a good name (and you'll find that, on the whole, the better racers are well named),” Ryall wrote in 1960, "I’m sorry to say this year's crop of two-year-olds has fared pretty badly... Ambiopoise... Nassue... Rulamyth...”
