Career
Schaffelhuber competes in the LW10para-alpine skiing classification using a sitting mono-ski and outriggers. She was selected for the German team at the 2010 Winter Paralympics held in Vancouver, British Columbia, Canada where she competed in four events. She won the bronze medal in the super-G finishing behind Claudia Lösch of Austria and American Alana Nichols in a time of 1 minute 38.25 seconds. She also finished fourth in two events, the super combined and the slalom, and seventh in the giant slalom. During the closing ceremony of the Games she carried the German flag. She skied at the 2011 IPC Alpine Skiing World Championships, held in Sestriere, Italy. She won the three gold medals, in the sitting women's super-combined, slalom and giant slalom, a silver in the team event, as well as finishing fourth in both the downhill and super-G. At the 2013 IPC Alpine Skiing World Championships held in La Molina, Spain, she successfully defended her title in the slalom, winning the gold medal in a time of 2 minutes 26.18 seconds. She won four other medals; silver medals in the giant slalom and super-G; and bronze medals in the super combined and downhill. She competed in her second Paralympics at the 2014 Winter Games in Sochi, Russia. She claimed her first Paralympic gold medal by winning the sitting downhill in a time of 1 minute 35.55 seconds. She won a second gold medal in the super-G, finishing first in a time of 1 minute 29.11 seconds. Competing in the slalom she was initially disqualified for not having her outriggers in a stationary position at the start of her first run and compatriot Anna-Lena Forster was identified as the gold medal winner in press releases. Following an appeal Schaffelhuber was reinstated and awarded her third gold medal of the Games with Forster winning the silver medal. Schaffelhuber won a fourth gold medal in the combined, with Forster again taking silver as the two German skiers were the only athletes to complete the race. She won her fifth gold medal, completing a clean sweep in the sitting events, by winning the giant slalom in a combined time of 2 minutes 51.26 seconds. She became the second athlete to sweep the alpine skiing events after Lauren Woolstencroft in 2010. For her performance at the Games, Schaffelhuber was awarded Best Female at the Paralympic Sports Awards.
