Back into the groove

My plantar fasciitis injury seems to have a mind of its own. Most days it doesn't cause me too much grief but on other days, even when I am well rested, I can feel the damn thing. It's more a niggle and a pest but I can do without it. I had a good run this mornning - about 7 to 8km of 1 minute fartlek bursts with 45 second recoveries.
