Slipstreaming effect
In the sports of running, swimming, motorsports and cycling, slipstreaming can give you a valuable advantage. By cycling in somebody’s slipstream, you use about 30% less energy than the person in front.
Maillot à pois rouges
The winner of the ‘King of the Mountains’ wears a white jersey with red dots (maillot à pois rouges in French), which is commonly referred to as the ‘polka dot jersey’. The jersey was introduced in 1975. The colours were decided by the then sponsor, Poulain Chocolate, to match a popular sweet which was wrapped in red and white.
