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?
