Lindsey Jacobellis, Snowboarder X Finals

The first woman to three-peat at Winter X, Lindsey Jacobellis famously blew a near-certain gold medal at the 2006 Olympic Winter Games when she showboated over the final jump. A year later, she blew a Winter X four-peat when she crashed at the line. But Saturday, she made history once again by winning and becoming the first woman to earn two three-peats.
