7.1 - half way there

I ran 7.1 miles this morning, farther than I have ever run before and halfway to my goal of running a half marathon on Memorial Day. I started experiencing gas cramps after the fourth mile, and they kept getting worse as I continued. And my stomach/back started aching from the bouncing motion - I think the excess skin of my panniculus is pulling on me and I am just not used to running for that long all at once. I wear compression pants, but I think a compression shirt is in order for these longer runs. Hopefully I will get better/tougher (and faster!). On the plus side, I burned over 1200 calories. Woohoo!
