Thursday 35 minutes (3 miles with BIG hills)

I ran around my mom's neighborhood while she watched the two little ones. She has one big hill in her neighborhood, which I looped around twice, and several smaller hills. I think cold running must take more energy because I was REALLY feeling the runner's hunger afterwards and I did not even run that long. Also- once again, I seem to run faster on hills. What's up with that? ;)
