This year I asked for a FitBit for my birthday. (For those of you that don’t know a FitBit is a pedometer, counting your steps, flights of stairs, daily active minutes, and approximate number of calories burned). I was excited and curious to clip on my FitBit and see just how far I was walking every day!
But, after a few, short days I was a little confused. I thought that about 2,000 walking steps = 1 mile, but I was getting FitBit read-outs on my phone that looked like this:
So, if you’ve been reading this blog for any amount of time, you can probably guess what I did next . . .Yep, I Googled the length of a walking step and discovered that this website (which seems legit to me) estimates that the average length of a person’s walking step is about 2.5 ft, which means that in order for a person with average walking steps to walk 5 miles, they’d have to take 10,560 steps . . . not 10,000.
Then, I started wondering how long my steps were (on average of course); compared to the published average of 2.5 feet/step. I used my FitBit output for 3 different days
and discovered that, despite my relatively short legs my walking stride length was pretty average!
Then, I started thinking about a project I used to have some of my students work one, which is now an activity on the NCTM Illuminations Site, called Walking to Class.
This summer, make a walking strides chart of your day (or a trip to and from the park, pool, etc.) but instead of measuring distance in steps, change the units from steps to miles using the average 2.5 foot length, or you could dust off a pedometer and calculate the length of your actual stride!
