Calculating Stride based on cadence?

[arsica23]

I used a foot pod with my garmin forerunner on the treadmill.  It reports on average (at least with today's run) that I take 168 steps per minute.  Does anyone know if it is possible to convert this to the stride length into the fit bit format?

Lets say you ran 1.1 miles in 10:15 minutes. I believe this is the math to derive your average stride length for today's run:

1. Convert time to decimal

10:15 = 10 + 15/60 = 10.25 minutes

2. Calculate total steps for the run

168 steps/minute * 10.25 minutes = 1722 steps

3. Convert running distance to feet

1.1 miles = 1.1 miles * 5280 feet/mile = 5808 feet

4. Calculate stride length in feet

5808 feet / 1722 steps = 3.373 feet

5. Input stride into Fitbit

3 feet

4 inches = (3.373 - 3) * 12

I love that you know this equation! I love math but am terrible at it. I am excited to try to figure out my stride based on your equation! Thank you. If I am not able to solve it can I post my actual stats and you can help me?

@arsica23 sure, post your numbers and I will quickly work out the numbers for you

@arsica23 I'm fairly good at math but sometimes it is easier to just use the web and go here. Here you enter your distance snd strp count, it will tell you the stride.

I simply  use the GPS tracking in t he Surge, this will give distance and steps.

Thank you @bbarrera My run was 44:27 min. 4.81 mi and spm=168.

@Rich_Laue. Thank you! I like the GPS function but was not sure if it would work on a treadmill. I run inside a bit more during the winter. Do you know how this function would work on a treadmill? This websitelooks like a great resource I'll check it out! P.S. Is that picture of you on a unicycle?😎

What the website give you?

@bbarreraThank you for your help on this!  I ran on the treadmill yesteday with both my Garmin forerunner and the Surge, and they were practically equal.  Only off by .03 mi.  Pretty great if you ask me!

When running on the treadmill doesn't it give you the miles ran, and fitbit will give the steps. 

Plug the two into the web page linked in last post

@Rich_Laue I use a Garmin Forerunner with a foot pod because I've found treadmills are inconsistent.

[arsica23]

@Rich_Laue. Sorry pushed send accidentally. So when I went in to the website I didn't trust the Fitbit steps because it was so far off what my Garmin read, and it requested my stride length--- besides I like trying new math equations...we are all to dependent on our computers. 😉

From what i read the foot pod still needs the stride to be calibrated.

The treadmill has a belt, and it's computer should have no problem telling you how much track has moved under the feet.
