Disagree. I run around 110km per week (on the low end of long distance training) on 6-7 days per week. You will not deplete glycogen unless you don’t eat or you do a hard workout every day. Recovery pace days are designed to help your body heal and recover while running. Running is not weightlifting. Running should not be strenuous to gain endurance (the best endurance pace and base building pace is far slower than strenuous - Jack Daniels and Pete Pfitzinger have great books explaining this in detail). These are all misconceptions. That said, people who are not actively fit shouldn’t run 7 days a week until they get comfortable with walking 7 days a week, because of some of the misconception you mention, and it’s likelihood to cause injury.
