In the 1901 Gordon Bennett Cup, Edge entered a special 17 litre Napier and was only able to test en route (she was completed 25 May, only four days before the event), Montague Napier serving as his riding mechanic; she overpowered her Dunlops, and fitting new (French) rubber led to disqualification, since they were not of the same nation of origin. In the concurrent Paris-Bordeaux rally, she retired with clutch trouble.
For the 1902 Gordon Bennett Cup, Edge's Napier was the sole British entrant; with his cousin, Cecil, as riding mechanic, she won at an average 31.8 mph (though by default, since the French entrants all fell out).
At the 1903 Gordon Bennett Cup, Edge had an 80 hp Napier, the Type K5, but was disqualified. Edge (with Arthur McDonald, manager of Napiers' Genoa factory, as riding mechanic) fared no better with the K5 in the 1904 Gordon Bennett Cup in Germany.

1903 Bio Note 
EDGE, S. F.- Born in 1868 in Sydney, New South Wales, Mr. S. F. Edge came to this country in his infancy. Road locomotion claimed his attention very early in life, and between 1887 and 1893 he figured very prominently and successfully in the cycle racing events of those years. In 1896 he started with a motor tricycle, followed by a Boll& and a great number of other cars. After touring for some time on Panhard cars he took up the Napier cars, upon which he achieved the great success of last year in the Gordon Bennett Race, which resulted in the Cup being brought over to this country, and which, thanks to his victory, is now held by this Club. Mr. Edge has turned his very considerable automobile experiences, both racing and touring, to practical account by taking a very considerable active interest in the British motor industry.
