Thirteen years and eleven days A skateboarder will become the UK's youngest person ever. Skye Brown, a Summer Olympian, will be 13 years and 11 days old when she participates in the Women's park category on August 4; skateboarding is also new to the Olympic program. When you turn 13, you can sign up for the Olympics. Your birthday is the only requirement: You have to be at least 1 year-and-a-day older than your country of residence at the time of the Games. If you were born in January, you would have turned 14 in December 2014. Brown has been skating since she was 3 years old. She lives in Bedfordshire, England, and goes to Bournville Academy. Skye is not the first athlete to compete in the Olympics at an early age. American skier Ester Ledecka, who is 26 years old and going through puberty, won gold in the women's giant slalom on Tuesday morning. She beat out more experienced competitors such as Tina Weirather of Switzerland and Martina Hingis of Switzerland — both of whom are now retired from competition.
