Haven’t tried it, but expect it would work, just a smaller version of doing laps Aron s a 400m track. There was also something about the movement of air too, treadmill is so stagnant (can get fan I suppose, not quite the same?)

Yes, I actually notice the air movement cooling me, as my basement is nice and cool in the summer.

I also reverse direction from time to time, so I get an even workout of "turn" during the oval parts of the loop. As I age, I've found I've had to increase my walking a bit, to maintain health. Maybe a 20% increase in walking time. :/
