Running outdoors vs. running on treadmill

Let me begin by saying I did contact Customer Support, it would really be helpful if the support personnel could speak better English 😞

 

Now, my issue is this - I have calculated my stride length and it's pretty much on when running outdoors.  However, running on a treadmill is different, my Surge is 1 mile or better in distance than the treadmill for a 3 mile run.  How can I correct this?

 

Thanks

When you ran outside did you use the Exercise mode called "Free Run"?

 

If you did then your stride setting vis-à-vis your distance traveled is irrelevant as it is overridden by the Surge's in-built GPS.

 

The thing about non-GPS runs, regardless of whether they are on a treadmill, an indoor track, or even in the great out of doors, is that a stride is not necessarily a stride.  Case in point, I also have a Surge and all of the historical data for roughly 2,000 miles worth of GPS tracked runs.  Cherry-picking a few of those runs I see the following:

  • A recent 5K race; stride length 4.4 feet
  • A recent 10-mile race: stride length 4.0 feet
  • A recent 10-mile training run at tempo pace: stride length 3.6 feet
  • A recent 10-mile training run at a slow pace: stride length 3.0 feet

Armed with the above data, and assuming I wanted to set my stride length so I could run on treadmill, what distance would I use for my running stride length?  Hint: the question is rhetorical, there is no one correct answer; it varies by day, weather, course, how I feel, and heck, probably the phase of the moon.

 

I used the above to illustrate how setting the stride length for your Surge is at the very best an approximation, and if it happens to be correct for any one run, it will likely be off, even WAY OFF on the very next run.

Yes, I do use "Free Run" for outdoor running, I didn't realize the GPS overrides stride length when doing this.  And this does make sense.  I will adjust my length and see how my treadmill run goes this afternoon.

 

Thank you!
