There were several classifications in the 1979 Tour de France, four of them awarding jerseys to their leaders. The most important was the general classification, calculated by adding each cyclist's finishing times on each stage. The cyclist with the least accumulated time was the race leader, identified by the yellow jersey; the winner of this classification is considered the winner of the Tour. In previous years, the team time trials only counted for the team classification, and not for the general classification, except for the bonifications. From 1979 on, the team trial also counted for the general classification.
