For the Love of Running

I think I'm starting to understand why people are so addicted to running. The half hour before I go out to run, I completely drag my feet, try to come up with excuses why I shouldn't go, etc. But half way through my run I realize that I'm fine, I'm not gonna die, etc. The last few minutes, I'm exhilarated. Then in the evening, I can't wait for my next run, wondering if I can go one minute longer, faster, etc. This running thing is so weird.
