Treadmill @ 8.7 . Seven minute mile?

Factual Questions
1

I just want to check my math.

If I set my treadmill to run at “8.7”, am I running the equivalent of a seven minute mile?

And a setting of “10.0” would produce a 6 minute mile?

Thanks!

2

8.6 would be closer

Yes.

Both of the above assume that the setting is in miles per hour.

Your welcome!

Yes. Bear in mind that running on a treadmill is easier than doing it outdoors though, so you might find a 6-minute mile on the treadmill feels easier than running it, say, round a track.

Since the OP’s question has been answered: why is this?

5

Whys I can think of: Air resistance (especially wind), road/track not being flat, not being able to pace yourself at the same speed throughout (run a little faster, tire yourself faster). Posture might also matter.

The belt pulls the foot and leg back to some extent rather than full muscle power pushing the body forward. Set the treadmill to about 1% grade to bring the effort up to outdoor levels.

wow. Glad I opened this thread. thanks

Another huge advantage of running on a treadmill is the opportunity to do so with air conditioning, especially if you live where there are hot, humid summers.

I think a treadmill also somewhat ignores the initial effort needed to accelerate your entire body mass to full speed. Not going to be much of a total difference if you’re running 6 miles straight, but if you’re alternating running short stretches with walking, it’s going to be a lot more difficult on a track.

I want to know how you can answer this question w/o knowing what units “8.7” is…

God knows - I ran Sunday and it was 95 and a billion percent humidity. It was like breathing pea soup. There comes a time every spring where I figure out the hard way that from that point on, early morning runs only.

I’m guessing miles per hour.
