Overheard this answer to " ever run a marathon"
Yep all 36,223* steps of it.
How many strides in a marathon depends on your stride length sure we know that. Has anyone every counted their strides for a whole race?
I think my HS 100 was 47 steps and a duck..
*I did not catch exactly the nember but it was started with 36 thousand
Let's assume the industry standard 180 steps/minute. Then 36,000 steps equate to a 3:20 marathon.

So then an industry standard 2;05 marathoner has a stride of 5 ft 8 inches!!
Standard for faster runners. If you watch marathons, you'll see that stride rates tend to be much lower.
If it's 160, then we're talking a 3:47 marathon.
Can someone clue me in on how to do this calculation? It seems there has to be an intrinsic assumption that I am missing (stride length?)
According to poster don't feed the troll we have an industry standard to adhere to of 180 spm.
Sure, I use a Polar RS800SD which records stride rate and from that I calculated close to 39000 strides for me.

Assuming 180 strides per minute you can calculate any stride length.
Alan
only 107 steps for me.
Why would you ass-u-me anything when it can be measured?
The last 3 columns are *spm @ end of lap *spm average for that lap *stride length (which is calculated in cm)
This is done with an accelerometer at a sampling rate of 1 hz.

Thank You Kevin52 so I guess this guy was in the ballpark with his numbers.
Your accelerometer has a sampling rate of 1 Hz? That means it only gets information once every 2-3 strides that you take, how can that possibly be accurate?
Oops sorry, I misspoke, you are correct.
The recording rate is 1 hz, I will have to look up the actual sampling rate (if Polar makes that info available).
In any case, on a treadmill, it is very close to what I can count using the clock on the wall for time.
