A teenage Souther California snowboarder made history by becoming the youngest winner in any winter X Games event. Chloe Kim defeated her fellow American snowboarder Kelly Clark. Chloe won the Women's Snowboard SuperPipe competition on Saturday in Aspen. Kim is only 14 years old! She has been riding since she was 4 and snowboarding is a big part of her life. The thing is Chloe wasn't even a little afraid or nervous before the competition. She was full of energy and happy, and she executed her run perfectly!
