Then in spring of 1947, the first dirt track race in Salzburg, organized by the just founded SAMTC (Salzburg automobile motorcycle and touring club), attracted 20.000 spectators on the trotting racecourse in Salzburg-Aigen. The SAMTC's first motorcycle race took place on the motorway near Salzburg on 6 July 1947. 1958 this race became the Grand Prix of Austria for motorcycles, which moved later on the motorway Anif-Grödig, also near Salzburg and in the end on the Salzburgring, where the race had been upgraded in 1970 to a world champion race.
