Why not indeed? Quite a lot of people do exactly that. The "run commute" is increasing in popularity here, or at least it was until covid.
At least for me personally, the reason I don't is that I'm not fit enough and it would hurt my hypermobile knees, but quite a few of my colleagues do run to work and to fetch lunch. I often jog to the offie or train station though.
Maybe, but overwhelming majority of people dont, whether before or post covid. Overwhelming majority of people walks to places and that includes people who like to jog.
Looking at past societies, people walked when getting to places, unless they were in usual hurry.
