David Ramos/Getty U.S. snowboarder Chloe Kim won the gold medal in the women's halfpipe with ease. Kim's first run was dominant enough to win her the gold medal through three rounds, but after winning the gold, she went for a third run as a victory lap. On her third and final run, Kim threw down back-to-back 1080s, her specialty, becoming the first woman to do so in Olympic history.
