Can I Record Running Power on a Treadmill?
You can record running power on a treadmill. Running power will be about 3-4% lower on a treadmill than running outdoors at the same pace because there is no need to overcome air resistance (drag). Wind conditions will also be disregard for indoor running automatically. Note that if you have the treadmill set to an incline, this is not detectable, so power will be underestimated.
