So, the treadmill was totally fine. True, I was wearing shorts in front of the students. My legs were definitely showing.

But, I just pretended it was completely normal. "Hi," I said to the kids, cheerfully.

"Hi," they said. I was pleased to note that they did not look horrified.

I ran for 30 minutes, and it was no problem. I'm doing it again tomorrow. This will be the key to my marathoning success. Thank you, High School Weight Room, I preemptively owe it all to you.
