Wind resistance
[wind ree-zis-tuhns]
/wɪnd rɪˈzɪstəns/
Noun
The force exerted by air against the direction of an object's motion, affecting its speed and energy efficiency.
Wind resistance is the force air exerts against a runner's forward motion, increasing with speed and headwind. It requires more energy to overcome, impacting pace and effort. Runners can reduce its effect by drafting behind others or adjusting their form. For example, a 10 mph headwind can slow a runner by 5-10%. Understanding wind resistance helps runners strategize during races and training, optimizing performance and energy use. It matters because managing it effectively can lead to faster times and more efficient running, especially in windy conditions.
