Having both plantars fasciitis and a strained calf in the last 6 months has caused me to ease up on the running a bit.
I run more tentatively, listen to my body more (especially calves, ankles, and feet), and take more rest days. I don't want to get injured again, so I'm running slower, shorter runs until I can build up some confidence and strength. Speaking of strength, I am also trying to incorporate strength and flexibility work into my training. I stress trying.
So, for my last few runs, I've run without my ipod, so I can "listen" to my lower body and pay attention to any possible pain. And, I kind of like it. My whole focus is on my run and how I'm feeling, aside from the mind wandering that happens naturally during runs.
This morning I had a nice, chilly 3 miler, felt pretty good, and I hope to get in another 4 or 5 tomorrow.
