Some places are arguably worse for running due to smog (unless running with an N95). Biking indoors with clean air is a much better option during fire season.
Well, sure, in some areas it might be the case (I've actually been running with a N95 the last week due to forest fire smoke here in Edmonton), but that wasn't really my point and the potential for smog doesn't make Peleton (as opposed to another stationary bike or treadmill) more appealing.
