Here’s How Much Slower You Run In the Heat

告诉你高温下跑步会慢多少

The same running workout feels harder on a hot day than on a cool one, and it’s not just your imagination. We really do slow down in the heat—at least until we’ve adapted to it—and it’s possible to calculate exactly how much.

同样的跑步锻炼在大热天做比在凉爽天做会让我们感觉更困难——这并是你假想出来的。至少在我们适应高温以前，我们(的速度)确实会慢，而且有可能准确计算出到底会慢多少。

The temperature calculator at Runners Connect is built with race times in mind, but it works just as well for figuring what’s up with your everyday run. Today, for example, I missed my early morning run and made it up later in the day in the 80 degree heat. The calculator tells me that at my speed, about 10 minute miles, I should expect each mile to take about 15 seconds longer today than it did on a 65-degree morning last week.

跑步者连接的温度计算器能够记录跑步的时间，它同样也可记录跑步中发生的情况。例如，今天我错过了晨跑，然后在今天白天温度为80度时进行了弥补。这时计算器告诉我，以我的速度跑完大约10分钟的里程，预计我会比上周早上，即温度为65度时每英里多花15秒。

The heat of an 80-degree day adds 20 percent to your time compared to your pace on the perfect 45 degree day, while a 70 degree day only adds 7 percent. That means your exact slowdown will depend on your original time. Because it’s a hassle to do percentage math with minutes and seconds, this calculator is a handy tool.

相较于在温度最佳的45度天运动，在温度为80度的一天运动会额外增加20%的时间，而70度时仅仅增加7%。即实际减慢的时间取决于你的原始时间。因为做分和秒的百分比计算是一个复杂的过程，而这个计算器只是一个便捷的小工具。

Humidity above 60 percent will slow you down even further, but that’s not reflected in the temperature calculator. Take it easy out there on hot days, and don’t be disappointed if your runs aren’t as fast as usual.

湿度超过60%会更大程度上降低你的速度，但这并不会体现在温度计算器上。热天出去的时候要放轻松，而且如果跑步速度不像往常那么快也不要失望。
