As a cyclist cuts through the air, he produces a slipstream that trails behind him, which is then used by the cyclist behind him to make it easier to pedal. About how much less energy does a cyclist using a slipstream use?

A cyclist using a slipstream from another cyclist will use about one-third less energy than if he wasn't using the slipstream. This strategy is why Olympic riders form a peloton, or group together, during races.
