Another day of 1.5 miles at 7mph. Felt maybe a bit harder than the day before, probably fewer calories to burn. But really I'm sure it's almost entirely psychological. I've been covering up the treadmill display so I can't hyperfocus on the timer / progress. When I finally uncovered it toward the end and saw I was at 1.43 miles, I could feel it getting harder as if my body knew I would let it stop soon and was pushing the incentive to not try and go further.

Again trying to analyze what it is exactly that inclines me to stop. My legs are a bit tight with the exertion, but it's not that uncomfortable. My breathing is sort of heavy and irregular, but I don't think it's failing to get enough oxygen. Best guess at this point is that it's sort of subconsciously distressing to not be able to breathe easily.

Scale said I dropped another pound, to 155.5.
