An incredible feat. A pregnant woman running a mile in under six minutes a week before her due date. The video went viral on social media, with millions of jaws dropping.

Makenna Myler who's originally from Australia but now lives in Orange County has been running five or six times a week during her pregnancy. Two doctors cleared her to keep running while pregnant.

The 28-year-old product trainer says her husband bet her a hundred dollars she couldn't break an eight-minute mile while nine months pregnant. She took the bet and crushed the goal by two-and-a-half minutes, coming in at five minutes, 25 seconds.
