...but I just ate half a donut so...

Today I ran 4.5 miles in 48 minutes at 6.1 and then walked 0.3 miles (5 minutes) as a cool down. My legs started hurting immediately during the run and now I am feeling pain in my left knee (usually the source of any running related pain). I may try a Hatha yoga class--per Mary's recommendation--tonight if Kid will sleep early enough. Also, I just ate half a sprinkle donut. So that's that.
