I had several friends who ran 15-20 miles/day 7 days a week pre- and through- COVID.
At a slow enough pace (relative to the individual), 15-20 miles isn't a hard run for many distance runners. (For the BQers in the bunch, their recovery pace was faster than my race pace. However, their race paces would be considered recovery paces for professional marathoners.)
