I’m paraphrasing: “Should I walk or run to get out of the rain?”
For me and maybe you, too, that’s an easy answer. I run if I don’t want to get too wet. I walk if I want to enjoy the feel of rain, especially after a long, dry summer. And if I don’t want to get wet at all, I use an umbrella.
I’m not looking for a scientific answer to this question.
But people have studied this scientifically. Null cites one study in which people wore a piece of cardboard over their heads and in front of them as they moved through the rain. The raindrop marks were then counted.
A more detailed study from NOAA’s National Climatic Data Center in Asheville, N.C., asked people to wear identical moisture-absorbing clothing as they moved at different speeds over 100 yards. Based on clothing weight, people who ran absorbed 40% less water than those who walked.
If you want to pursue more detail on a subject that already has taken way too much space here, go to this website, use the calculator and find your best speed to walk or run in a downpour.
