I do 5-10k runs once or twice a week. While my legs inevitably get tired, last time they felt unusually heavy before even hitting one kilometre. Especially the ankles which felt solid rock.

      I don’t remember! Sometimes when I don’t feel lazy I stretch beforehand (I should be more consistent). But I usually begin by simply walking then elevate the intensity progressively.

      My biggest suspicion was breathing. I somewhat remember that I wasn’t properly inhaling and exhaling, sometimes would hold my breath unconsciously.

      This morning I made sure to stretch and actively breathe. Didn’t face an issue.
