If it were five miles, I wouldn't care, but regular trousers pull on me in various directions, I get sweaty, I'm wearing my clothes out, and I look wrinkled upon arrive. Plus I probably smell.

That is about my shortest route - 26 mi RT. I can't imagine doing it in street clothes. You can get pretty sweaty in 13 mi even in cool weather.
