Martinelli run

Did the Martinelli out and back loop yesterday morning.  I had 6 left calf twinges (like someone was sticking a knife in there), and a little tightness in the right lower calf, and my thighs were killing me, but otherwise I felt great.  I did 8 minute miles for the most part.  My thighs were really sore afterwards, but I think that was left over from the race last Sunday.  The sharp pains were very few, and considering that two weeks ago I couldn't run at all, I will take a few sharp pains here and there.  I really must try to do some more stretching.  I tried to dedicate a couple of half hour segments to stretching this last week, so I think it is helping.
