Background: Lindsey Caroline Vonn (nee Kildow ; born October 18, 1984) is an American World Cup alpine ski racer on the US Ski Team. She has won four World Cup overall championships--one of only two female skiers to do so, along with Annemarie Moser-Proll--with three consecutive titles in 2008, 2009, and 2010, plus another in 2012. Vonn won the gold medal in downhill at the 2010 Winter Olympics, the first ever in the event for an American woman. She has also won a record 8 World Cup season titles in the downhill discipline (2008-2013, 2015, 2016), 5 titles in super-G (2009-2012, 2015), and 3 consecutive titles in the combined (2010-2012).
Context: At the Vancouver Winter Olympics in 2010, Vonn planned to compete in all five women's alpine events. On February 10, she revealed she had severely bruised her shin in training the previous week. Vonn said the pain from her injury was "excruciating" and she would have a difficult time competing at the Winter Olympics. Due to unseasonably warm weather and resultant poor snow conditions, many of the Alpine skiing events were moved back, giving Vonn additional time to heal. On February 17, in her first event, Vonn won the gold medal in the downhill at Whistler Blackcomb, beating longtime U.S. rival Julia Mancuso by 0.56 seconds and becoming the first American woman to win Olympic gold in downhill.  In her second event, the super combined, Vonn finished first in the downhill portion of the race. In the slalom portion, however, she crashed when she failed to get her ski around a right-hand gate. Vonn said her shin wasn't the problem. Gold and silver were won by Maria Riesch and Julia Mancuso respectively.  In her third event, the super-G, Vonn finished third behind Andrea Fischbacher and Tina Maze, 0.74 seconds behind Fischbacher's winning time. Afterwards, Vonn said she didn't ski the last part of the course as aggressively as she could have and lost the race as a result. In her fourth event, the giant slalom, fog affected visibility. Vonn crashed in her first run, resulting in a broken fourth finger and Vonn's disqualification from the event. In her fifth event, the slalom, Vonn lost control and straddled a gate, disqualifying her from the event.
