My legs

I went for a run last night. I intended to run three miles, but about 3/4 of a mile out my calf muscles began to stiffen up and then to hurt. I walked home. The pain is concentrated on the inside of each calf - more on the right leg than my left. I have a lopsided gait and my right leg is the one that comes down gracefully, my left leg thumps down. Not sure what it all means.
Last summer I always waited two days between runs, lately I have occasionally only waited one day. I am hoping that I just overdid it and that a few days rest and I will be OK.
I did the TV yoga class "Inhale" this morning to make up for my laxness. If you want to start the day with a real good sweat, I have to recommend "Inhale." 6 a.m. on the Oxygen Network.
