Ouch!

Today I started running again, and my body is certainly reminding me that I've taken the last month and a half off.  Back when I was still in school, I was running 3 miles straight, and working my way up to 4, but today I couldn't even run a single mile without stopping.  I did run an entire mile, but I had to take a couple breaks.  Slightly upsetting, but I'll get back into it.  Gotta keep a positive attitude, right?
