Oh, for sure. I mean, traveling 25mph into a 25mph wind on a bicycle would take something between 1,700 and 2,000 watts. You'd be producing so much heat you could take your shirt off.

The windchill (relative) is as I said much earlier, around 5ºF, give or take. That's cold. If the wind chill were recalculated to say, -1ºF, would that make an earth-shattering difference?
