Quad (figure skating)
A quad, or quadruple, is a figure skating jump with at least three but less than four revolutions. Most quadruple jumps have 3 1/2 revolutions; the quadruple Axel has 4 1/2 revolutions, although no figure skater to date has completed this jump in competition. The quadruple toe loop and quadruple Salchow are the two most commonly skated in the discipline. Quadruple jumps have become increasingly common among World and Olympic level men's single skaters, to the point that not having one in a program has come to be seen as a severe handicap. The first person to land a ratified quadruple jump in competition was Canadian Kurt Browning in 1988. In 2002, Miki Ando became the first woman to do so, and she remains one of only two women to have landed a ratified quadruple jump in competition.
Ashley Caldwell
Caldwell then suffered from back to back ACL tears, missing the 2012 and 2013 competitive seasons. Upon returning she claimed the silver medal at her first world cup event in China earning a spot to the Sochi Olympics. She placed 10th place after a bad landing on her first finals jump. She competed again in Beijing in December 2014 winning gold, alongside her 19-year-old teammate Kiley McKinnon, who won silver. She became the first female skier to land a quadruple twisting triple back flip at the 2017 World Championship in Sierra Nevada, Spain. Caldwell won the event alongside teammate Jon Lillis.
