Lately I have been running very short distances. Only for about 4 or 5 minutes. It makes my legs feel great and gives me a boost. Seems to be working for me, I feel strong. I wonder if the longer runs were wearing my body down instead of building it up.
It feels very natural nad is very much a intuitive thing, I run as much as I feel like running, disregarding what any of the norms or "right ways" to run are. Its based on my personal experience and intuition.
