From Muhammad Ali to Michael Jordan: The Greatest Comebacks in Sports History

This Saturday, Lindsey Vonn makes her comeback in the Super-G in St. Moritz, five years after her retirement. With Vonn's return, one of the most successful female skiers is back in the World Cup. Her illustrious career boasts 82 World Cup victories and a gold medal from the 2010 Olympics. The 40-year-old American is among many prominent athletes who have un-retired.

Martina Hingis: Three Successful Attempts

At just 22, she first retired due to foot problems. By 2003, Martina Hingis had achieved more than Swiss tennis ever dreamed possible, becoming the youngest world number one at 16 and winning five Grand Slam titles. She made a comeback in 2005, winning three tournaments, but not another major. Two years later, she was banned for doping (cocaine) and retired again. This move was not final, as she returned to the tour between 2013 and 2017, this time focusing on doubles and mixed events with great success, adding nine more major titles and leading the doubles world ranking.

She became a world record holder at 14 and an Olympic champion at 17. Dara Torres retired from swimming at 25, only to return seven years later at the 2000 Sydney Olympics, where she won her third and fourth Olympic gold medals as well as three bronze medals. Her second comeback was even more spectacular: as a mother, she qualified for the Olympic US team for the fifth time, becoming the oldest swimmer to do so. In Beijing 2008, at 41, she claimed three silver medals - two with the relay and one in the 50m freestyle.

George Foreman: The Champion Grandpa

George Foreman won Olympic gold in heavyweight boxing in Mexico City in 1968 and retired in 1977, later selling over 100 million grills and becoming very religious. A decade later, “Big George” returned to the ring, knocking out the 19 years younger Michael Moorer in Las Vegas in 1994, becoming the oldest boxer to win a heavyweight title. In his 81st and final professional fight, which marked his fifth defeat, he was 48 years and 316 days old.

Lance Armstrong: Defeating Cancer

Lance Armstrong’s comebacks are as complicated as his life. In 1993, after winning the World Championship at just 21, the Texan was diagnosed with testicular cancer. After recovery, he returned in 1998 and dominated the Tour de France, winning seven consecutive titles. However, they were tainted victories as all were stripped due to doping.
