Hey, I can run!

Well, as you know I've been on here complaining that I havent felt any better since quitting, but I've seen my first positive sign today. I'm not much of a runner, never really liked running even though I've played sports my whole life. But today I decided to go for a run,stop smoking, as I've done a couple of times a week throughout the summer. Its about 3/4 of a mile around my block, and normally I would run about halfway, and then walk for about 2 minutes before I could run again. Today I started running, got to the halfway point,smoking cessation, decided I could keep going, made it ALL the way around the block..and kept going half way around it again. I was running with the biggest smile on my face. Now, I'm not a marathon runner by any means yet, but I can now run at a decent speed for over a mile without passing out. Seems like a good sign to me. I can imagine what it will be like after a few months.
