Jules Audy was born in Montreal on September 2, 1912. Jules was known as the "Blonde Flash" because of his blonde hair and his fierce attacking as a 6-day racer. For years he was the darling of female fans who followed six-day racing in Canada and the USA. Audy's skills as a six-day racer were in demand by the promoters of the six-day racing circuit. He was a classy sprinter who was not afraid to attack during a jam. Because of his small stature and his baby face looks the media of the day characterized him as the "blond flash whirlwind". He was adept at moving in and out on the crowded track with skill and daring.

Jules rode his first professional race in 1931 when he was just 18 years old teaming up with the Dutch veteran Piet Van Kempen for a six-day race in Montreal. He impressed the spectators and his fellow racers with his exhibition of speed and stamina finishing the race in second place. His next six-day race was in Minneapolis where he teamed up with Torchy Peden after they both lost their original partners because of illness and injury.

Immediately there was some magic between Peden and Audy. Peden, who was over six feet and Audy who was just five feet five inches appeared to be a miss-match especially during the hand sling of the Madison. The team went on to win the 1931 Minneapolis six-day. This partnership lasted over 11 years and the team of Peden and Audy became one of the most victorious teams in six-day racing. They partnered 32 times and won 9 races as a team. The team of Peden and Audy is ranked 18th place on the all-time list of the six-days most victorious teams.

Over his professional career as a six-day racer Jules Audy participated in 110 six-day races and won 14 of them. Audy's career lasted from 1931 to 1950. His last six-day race was at Madison Square Garden in 1950.

Jules Audy was inducted into the Temple de la Renommee (Hall of Fame) of the Federation Quebecoise des Sport Cyclistes in 1988.
