Ouch! My calves hurt.

So here goes for my first update...

On Sunday I ran 6.35 miles at a brisk pace (for me). Not sure how I ran it that fast, but I hope I can keep it up for the full 13.1 in a few months. I felt really good afterward. I gave myself some time to do a lot of stretching so I wasn't sore at all. Yesterday I did a "cross" day and did the elliptical for a bit at the gym and then some upper-body weight training. That's not so much for the half training and more for my aim of having rockin' arms for my wedding. (P.S. for those counting down, it's officialy less than 5 months away!!) This morning I ran 3.5 miles - this is where the calf pain comes in. Almost immediately after I started running, my calves balled up. I stopped to stretch them out a bit, but it didn't help. Luckily, I did an out and back route that I had mapped out beforehand, so I had no choice but to complete the distance. I was so happy when I finished.

Does anyone know of any good calf stretches? I did the only one I know - placing the ball of your foot against the wall and leaning in - but that hasn't helped me.

Also, does anyone find that sometimes after having a really good run, your next run is slow and somewhat painful?
