Yesterday, I ran 3 WHOLE MILES without any walk intervals! I haven't done this since the middle of 2011. Honestly, sometimes I didn't think I would ever be able to do this again. I had no IT Band issues, no left shin/calf issues, and I didn't even feel the tenderness in my left foot (from dropping the pizza stone on it last Friday) until the very end of the 3rd mile. It was even a little warm outside so I could wear short sleeves!
I will never, ever take running (or biking, or swimming) for granted. Not ever again! :)
