It depends on the intensity level. In the pandemic of 2020, I ran 26.2 mile runs at an easy effort for 5 weekends in row in the spring and 6 in the fall, generally with my easy effort getting faster as I went. Rather than the sequence of big runs wearing my out, I was getting stronger.

Now, if I had tried to run every one at "race pace", I would likely be trashed or injured by the end from insufficient recovery.
