From 1974 to 1977 the races of Targa Florio were valid for the Italian championship. The champions, who had help to create the legend of Targa Florio, were fewer than before: the race was becoming more and more a regional competition. The races from 1974 to 1976 kept on attracting fans from everywhere, although in a minor tone.

In 1977 the race should consist of 8 laps, but it was interrupted during the fifth lap, because of an accident along the route: it was the bitter confirmation that the Circuit of Madonie Mountains was not able to bear this kind of competition. The judgment of International Committee was confirmed: the 15th of May is the last date of this historical competition. Today it can be still considered as the oldest race in the World, thanks to all of the sporting events, which celebrate the Circuit every year: Rally or Targhe Storiche.
