Here’s an article about a mud-run team that is about 50% in a skirt:
Here I am completing my first Spartan Sprint in a skirt. People thought I was flexing massive Girl Power muscles, but what about the guys who did it in kilts? Face it: clothes are cooler without a crotch.
The only place where my skirt was a bit of a drag was while swimming the lake. Otherwise, it zipped through everything on the course. You can do it in a skirt!
This, by the way, is my favorite workout skirt – Athleta’s Whatever Skort.
