I am so glad I ran across this. I was on the elliptical for 60minutes the other night. Someone suggested it might be meters which would have only equaled 2miles or so. That didn't make me happy.

Thanks for the posts!!

This is a great post.

So today on my Elliptical I did
Time 45:09 ~~ 6688 Strides ~~ 435.2 Calories

So if I calculated this right that almost 4 miles.

I am such a number girl that I need to know miles....once I found out the equation...I am happy just to increase my revoultions, I always want more and further than last time......all that for nothing...but know I now how to determine it...

Thanks Coop! that sounds too complicated for me. I think I will stick with strides rather than circumference of the wheel. but thanks for the info anyway. Pat

Wow! Is that intense or what!? I'm just glad mine has miles on it! And I like math!!! emoticon

Enjoy life to the "nth" power! If you have goals and aspirations set forth to do them now. Life is too short. Like Nike says...."Just Do It"

Procrastination is not an option. Never say never. Tomorrow is not promised to us. Enjoy!! As my cousin says...."Do you"!!!

you also need to take into account the wheel diameter...below see email I rec'd from Nordic track...for my machine(not the ex below mine is 851.6)
Use simple geometry to determine how many Nordictrack revolutions equal one mile.

First, measure the radius (r) of the encased wheel (this is the distance from the center to the outer edge). For improved accuracy, I measured from the center to the middle of the axle that attaches to the foot platforms. On my machine, the radius was 10 inches. But we really need the diameter, which is 2(r), or 20.

So, we have the first part of equation, diameter (d): 20h

In order to determine the distance that the wheel would travel if it rolled freely, I need to measure to know the circumference of the wheel. This is the total length as measured all the way around the wheel, like you would get if you wrapped a tape measure around it.

Herefs where the geometry comes into play: since I cannot wrap a tape measure around the wheel, I use this formula to calculate the circumference (C):

C = d(PI)

PI is that weird number that you remember from school. I wonft even bother with any details; for this explanation wefll just agree that it is an important number and wefll say it is 3.14159265.

So, the equation starts to take specific form:

C = 20(3.14159265) or C = 62.831853"

Now that we have the C, we can calculate the miles per revolution. To do this, first convert C, which is in inches, to feet:

62.831853" = 5.236

Now we know that every time the wheel revolves one complete turn (a revolution), we theoretically have traveled 5.236 feet. How many equal a mile? One more calculation:

5280 feet / 5.236 feet = 1008.4 revolutions

So, to travel one mile on the Nordictrack you have to pedal 1008 (or so) revolutions.

I found it MYSTERYROSE! It says it is a 16 inch stride lenght so that shoud be 32 inches instead of 3 foot. Thanks again. Pat

You might want to just do a Google search for your model and see if you can find comments by other people who have bought the same one. Someone may know somewhere.

No I haven't found stride lenght in the manual either.But both of you have you have been a big help. I will just have to assume mine is a 3 foot stride lenght too and go from there. It's an estimate any way. Thank you so much ! Pat

Ah the instruction manual is always a good place to start, lol. Mine didn't have mileage in it, but it did tell me the stride length.

If you know the stride length of your elliptical it's just a simple math equation. I'll use mine as an example.

My elliptical has a 3 foot stride length. There are 5,280 feet in a mile. Divide 5,280 by 3 and I get 1,760. So I need to make 1,760 revolutions on my elliptical to go a mile.

Just because I'm a dodo, does the instruction manual have anything to say?

I have a Proform 500F Elliptical and the DISTANCE shown is in revolutions per minute. Anyone know how to convert those revolutions to miles??
Thanks, Pat
