    I used to collect a lot of pennies from my readers and donate them a worthy cause at the year's end. However, until there is a clear solution to prevent PayPal from taking half the donations, this feature is down. Keep the pennies in a jar. ;)

Running Vs. Walking Through Rain

Here’s something to consider, especially those of us living in the Pacific Northwest where rain can–at times–be an everyday occurrence… Made up scenario:

Looking your very best, you depart for a fancy shin-dig, your car is parked 100 yards away and suddenly a hell-storm of rain begins to pour from above. You’re already late so waiting it out isn’t an option and your umbrella doesn’t exist. So, what do you do, walk or run?

A week ago I made a dash for my car during a down-pour. Once in the car my friend (who had walked) asked if I thought running really kept me more dry. My instincts said yes, of course running through the rain will leave you less saturated than walking. Then, after more thought I began to second-guess myself. Will running through the rain really keep me more dry? The answer is no, running through the rain will not necessarily keep you more dry than another person walking the same distance through the same rain.

A physicist at the University of Udine, Italy, Alessandro De Angelis calculated a best-case scenario where a sprinter moving at 22 MPH does get less wet, but only about 10 percent less wet than a casual walker moving less than 7 MPH.

In Conclusion, running from rain is only worth it for Olympic sprinters… This dude should be walking:

  2. Hey,
    Just an add-on to your comments! The same question popped in our heads on our way back from dining at a place near-by. No umbrella and a short distance my hubby decided to walk and I to run…got home and googled! So I got something here that might interest you :) .

  3. *Gaaarrgh* If running takes you from being outside in the rain for 20 seconds instead of walking in it for 60 seconds, shouldn’t that increase your dry-factor significant!?
