First day of school

I ran on the treadmill last night. It was the first day of the semester yesterday and I had to teach and then go to four different meetings. There was no way to get in a run before leaving the office. Plus it was raining/snowing when I did finally leave. So the treadmill it was. The run wasn't great. Two years ago I fell down the stairs at my house (call me Grace) and my right hip has never been the same. For whatever reason, it was bothering me during the entirety of my run last night. I'm hoping this is not a symptom of a larger problem. I think I'll be looking into those new shoes soon.
