Research shows COVID-19 social distancing must be increased while hiking, running and biking!
Distances to avoid particle contamination must be increased up to 65 feet as speed is increased and/or by moving to the side of the slipstream of the person in front of you.
The latter is difficult or impossible to do on narrow forest trails and roadway shoulders, so be safe when seeking a breath of fresh air and some exercise outdoors!
This article in WIRED magazine explains why the standard 6 feet of social distance isn't enough as we breath harder and move more rapidly.
Enjoy our public lands and roadways but do so safely!
