"If not you, then who?"

Today, the plan was 3x200 and 3x150 (accelerations). I hit :27 and :28. I stopped at the 100 mark on the 3rd 200 (:13/:14) because my left calf starting acting up again. For this reason, I did only 2 150s...in 19 and 20. I would be lying if I said I wasn't nervous. I tried to get an appointment with sports masseuse but I had not such luck. I am now wondering whether I should take tomorrow off or just jog. I just don;t quite feel sharp. So much for splitting 53.1 like last year. We'll see. I have to be positive. Like I sometimes say, "If not you, then who?"
1.1 warm-up and cool down.

Yesterday, Tuesday 4/20/10, I did 3x300 just to get my legs going a bit. Goal pace was :45. I did: 44, :46, and :45. 1.1 warm-up and cool down.
