I am actually unconcerned that the people I meet while I am out walking / jogging / running / cycling do not maintain a distance of more than 6 feet from me.
The main reasons are that there are no new confirmed cases in my neighborhoods, I come across only one or two people per hour, and we don't spend more than one or two seconds near each other anyways. I am not wearing a mask and I have not seen anyone else wear a mask in the outdoors.
Of course, maybe your neighborhood is a hot bed of confirmed cases and people should behave differently. Whether you know if your neighborhood is a hot bed could be unknown because some places are lying about that.
Why you’re unlikely to get the coronavirus from runners or cyclists:

Fortunately, increasing your distance, decreasing the duration of your exposure, and improving the ventilation of the air around you can all lower your risk. And being outdoors generally helps you do all three.
“The risks of virus transmissibility in the air outdoors is likely quite low in those contexts, although this risk hasn’t been definitively measured,” Rasmussen said. “Outside, things like sunlight, wind, rain, ambient temperature, and humidity can affect virus infectivity and transmissibility, so while we can’t say there’s zero risk, it’s likely low unless you are engaging in activities as part of a large crowd (such as a protest). Solitary outdoor exercise is likely low-risk.”
