In the Tour de France, there has been an official competition for young riders since 1975. Excluding the years 1989 to 1999, the leader of the young rider classification wore a white jersey. The requirements to be eligible for the young rider classification have changed over the years but have always been such that experienced cyclists were not eligible, sometimes by excluding cyclists over a certain age, cyclists who had entered the Tour de France before, or cyclists who had been professional for more than two years. In the most recent years, only cyclists below 26 years are eligible.
