Compared to running outdoors the treadmill is so much harder. My heart rate is higher on the treadmill than outdoors for less of a pace. For example 8:00/mi on the treadmill feels like 6:50/mi outdoors. Why is this?
am I burning more calories with a higher heart rate in doors even though my pace is 1:00+/mi slower? what gives.
80mpw on the treadmill is hell by the way. and no I'm not running when it is only 10 out (-5 with windchill). it's only November....
