River Tam, Batman, and a Cirque du Soleil performer had a child: Kacy Catanzaro. Watch this 5-foot, 100-lb woman stomp all over a test of strength and endurance that has defeated Navy SEALs, football players, and other muscly types.

As much as I love seeing her show off her superhuman physical prowess, my favorite part of this is the announcers and crowd. The announcers refer to her as a woman, not a girl. They talk about how she’s the first female competitor to complete the course, but that’s it. No, “look at this little girl go!” No comments about how her looks. They just treat her like a competitor. And the men in the audience seem to see her the same way.

Possibly because she might be able to kill them with her brain if they step out of line, but in a world where female athletes are expected to do bikini shoots, or where announcers can’t talk about them without talking about their looks, I like to think that this is progress.
