Yesterday I ran five and a half miles on the treadmill and I took the advice of my reader Jan and turned the GPS off on the Garmin first, and it finally worked. Well it measured the run, but it wasn’t terribly accurate. But in the interest of science, I decided to take multiple measurements before sharing my results.
Obviously I win for failing the most at scientific experiments but whatever. I did the exact same thing today and I turned off the GPS on the Garmin and then got on the treadmill and I ran 6 miles. The only thing that I did differently was start and stop it a few times before I actually got going but that was because I was trying to get the treadmill up to speed.
Maybe it turned the GPS back on when I re-started it but who knows. I would like to tell you that I’m going to continue this experiment in the next few day but that is not going to be the case because
And it hurts.
Anyway, since I only have the results of one day I might as well share them with you and then once this stupid rash from the HRM goes away, I’ll try again.
So there’s that. Depending on which statistic you trust most, there is a difference from a few seconds to about a minute per mile and a pretty big difference in distance for the Garmin 620.
Now for the record, my treadmill is used and MacGyver and I did purchase it at a garage sale. That being said, I did have it checked out and it works perfectly and has less than 125 miles on it. My Garmin has been fairly accurate and in the 1 1/2 years that I’ve owned it, I’ve had no issues with it at all but I haven’t used it on the treadmill before either.
I think the pace conversion chart is fairly accurate too but I will say that when I’m running on my treadmill I don’t feel that a 1% incline is all that much harder than no incline. A 2% incline however feels like a big difference.
In my opinion, the conclusion of this scientific experiment is that the treadmill is the most accurate. I’ve been running for many years and honestly that 5.5 mile run ‘felt’ like a 9:12 pace and I think I’m a pretty good judge of what my pace is based on how it feels. But my results are in no way conclusive and I’ll need to conduct many more tests.
You know what that means don’t you? More running for me, in the interest of science of course.
So, which method do you think is more accurate in determining distance, pace, etc. when running?
What do you use to track your time and pace?
