Just how ridiculously fit is Milla Bizzotto, a 53-pound 9-year-old from South Florida?

She’s so fit and that she recently completed the Battlefrog race BFX24 — a 24-hour U.S. Navy SEAL-inspired obstacle course that requires participants to race 36 miles, swim eight kilometers and conquer 25 obstacles that include a rope climb, crawling under barbed wire and climbing a 12-foot wall for six laps. She slept between 2 and 6 a.m. and counts the hardest part of the race to have been the “Platinum Rig,” in which participants swing between ropes, rings and monkey bars without touching the ground. All of which leaves one question: Why would a tutu-loving 9-year-old want to do this?

The answer is simple. She was being bullied at school.

“People would call me names and say I wasn’t a good player,” she 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.”

So she hit the gym — hard.

Her father, Christian, owns a gym and she began training five days a week for three hours a day to prepare for the race, with the competition’s sponsors allowing Milla to compete as long as he was beside her.

“I’m fearless,” she told the Herald. “And knowing I’m inspiring people makes me more fearless. It is hard, but that doesn’t stop me.”

Milla had other help along the way, too. She raised money for her gear — $1,500 for compression socks, waterproof lights, gloves and hydration packs — with GoFundMe. “We have a lot of supporters, which is awesome,” her father said. “A bunch of members from the gym were there all day and all night to provide food, water, massages and a place to sleep.”

It looks as if she’s going to keep this up, too. She competed in her first BattleFrog last November, over a 15k course designed for adults.

“I don’t want to play video games,” she told the Herald. “I don’t want to Hoverboard. I don’t want to do things to make life easier. I want to be comfortable being uncomfortable. I have one body and it’s all I want and all I love.”
