At the height of his career, in the 1920s, he was said to be more popular than Mussolini and it was decreed that all express trains should stop in his home town Novi Ligure, an honour only normally awarded to heads of state.

[1] Born in Novi Ligure (province of Alessandria, Piedmont), Costante Girardengo turned professional in 1913 at the age of 20 for the Maino-Dunlop team after impressing as an amateur the previous year by finishing runner up in the Tour of Tuscany.

Much of the professional cycle racing was stopped after 1915 because of the First World War and it was not until 1918 that Girardengo took another win, taking the first of his six victories in Milan–San Remo, a record which Eddy Merckx eventually eclipsed over 50 years later.

His post 1918 form was all the more remarkable as during the First World War Girardengo had contracted Spanish flu and nearly died, his manager believing a survivor of that disease could not race properly refused at one point to renew his licence.

1923 was undoubtedly Girardengo’s best year with 16 victories, he took his second Giro d’Italia win including eight of the ten stages as well as many of the top Italian one day races.

He also became the head coach of the Italian national squad for a time, advising Gino Bartali when he won the 1938 Tour de France.
