DON’T let the tutu fool you — Milla Bizzotto is one bada** little girl.

The 9-year-old from South Florida weighs just 24kg and is making headlines as the youngest competitor to complete the Battlefrog race BFX24, a 24-hour obstacle course designed by the U.S. Navy.

She raced 58 kilometres, swam eight kilometres and completed 25 obstacles which included a rope climb, crawling under barbed wire through mud and scaling a 3.6 metre wall, for six laps.

She only slept for four hours between 2am and 6am of the race, and was the only competitor under 18.

Bizzotto says she got into fitness after being bullied by her classmates.

“People would call me names and say I wasn’t a good player,” the girl told the Miami Herald.

“I didn’t want anyone else to go through what I did. I want to set an example and show other kids that they can do or be anything they want.”

She says it helped her deal with bullying at school. Picture: E Ricabal Photography

She began training with her father, Christian, who runs a gym, and started training five days a week, three hours a day to prepare for the race. She previously completed a Spartan race with her grandma and father.

Bizzotto hopes her accomplishment will help fellow members of the “iPad generation” get up off the couch and go outside and play.

She adds: “I love what I do. I want to do it forever.”
