人类为什么能成为地球上最厉害的长跑健将？

Each year, a small town in Wales holds the Man Versus Horse Marathon. It's a 22-mile race between riders on horseback and runners. And, while horses often win, humans will sometimes prevail.

威尔士的一个小镇每年都会举办“人马长跑大赛”，由骑马者和跑步者共同参与，赛程约为35公里。虽然骑马者常常胜出，但人类有时也能获胜。

So what makes humans such endurance running superstars?

那么，人类为什么能成为长跑健将呢？

人类为什么能成为地球上最厉害的长跑健将？1

The secret weapon is our sweat. We have 2-4 million sweat glands all over our body, which means we can run and cool ourselves at the same time. Having no fur is also a huge plus.

我们的秘密武器是汗液。人类全身覆盖着200万至400万个汗腺——也就是说，我们能够一边跑步一边降温。另外，没有皮毛也是一大优势。

In contrast, dogs rely on panting to cool down, and other animals, like horses and camels, also sweat, but less effectively. As a result, they overheat faster and must slow down sooner.

相较而言，狗要靠喘气降温；马、骆驼等其他动物虽然也流汗，但降温效果不如人类。因此，它们的体温会更快过热，需要尽早减速。

The mechanics of our running stride also makes us particularly well-suited for endurance running. A human's running gait has two main phases: Aerial when both feet are off the ground and Stance when at least one foot touches the ground.
