FreundinSonntag has a treadmill but every time i run on it, i punch in my GPS measured outdoor pace and i can't run half as far as i'd normally expect to. Is the issue the slight incline? Is it that I'm running at a constant speed where, as GPS shows, i kind of fluctuate up and down for an outdoor run? Or, could it be the treadmill? My working theory is that the motor isn't strong enough to run at a constant speed, so when i footstrike it slows down and when i push back off it speeds up, robbing the spring from my step and making me work harder.
I suppose objectively, its NBD, if i can work up a sweat, get winded, feel some burn, its doing its job BUT it frustrates me as i try to track my splits!
