My workplace just instigated a "Walking For Wellness" program, and to encourage people to sign up they offered a free pedometer to the first 100 who did. Although the program is geared mostly to the office staff who sit in front of their computers all day and get no exercise I signed up because I wanted the free pedometer.
Now I've always been able to walk really really fast. Five miles an hour is my comfortable cruising speed. Since I'm short I've always assumed I take short strides but move my legs quickly.
Not so. One of the scientists in my building helped me calculate my stride length. Turns out my stride length is huge, 36 inches. The scientist was surprised and so was I. My stride length is longer than his, and he's over six feet tall. Of all the people for whom he helped calculate stride length mine was the longest.
I never would have guessed this myself but it's good to know.
