When two or more experienced cyclists ride together, they often try to take advantage of "drafting." Drafting is the act of one cyclist riding closely behind another cyclist, taking advantage of the absence of wind created in the pocket behind the rider in front who is pushing through it. Think about the wake of a boat that curves away behind it. Now imagine the wind making a similar pattern behind a biker. Every cyclist (or moped, or car, or truck) produces a wake — a pocket of air — in which the wind resistance is noticeably less. The cyclist behind feels considerably less resistance, making pedaling easier. Sometimes cyclists work together, sharing the wind-blocking duties so that someone is always getting a rest. This allows them to reach their destination faster and fresher.
