From a prodigiously talented 15-year-old to the most decorated female skier of all-time, Mikaela Shiffrin has done quite a lot in only 12 years. The American skier won her record-breaking 83rd victory Tuesday in her 238th race on the World Cup circuit, the globe-trotting competition for the best skiers on the planet. Shiffrin, who broke a tie with former teammate Lindsey Vonn by winning a giant slalom in Italy, has also won two Olympic gold medals and one silver, plus six world championship titles and five more medals from that biennial competition.
