Greg LeMond is a former professional road racing cyclist, entrepreneur, and anti-doping advocate. LeMond began his professional cycling career in 1981.

In 1983, he became the first American male cyclist to win the Road World Championship. LeMond won the Tour de France in 1986; he is the first non-European professional cyclist to win the Tour. He was accidentally shot with pellets and seriously injured while hunting in 1987. Following the shooting, he underwent two surgeries and missed the next two Tours. At the 1989 Tour, he completed an improbable comeback to win in dramatic fashion on the race's final stage. He successfully defended his Tour title the following year, becoming one of only seven riders to win three or more Tours. A two-time winner of the Road Race World Championship (1983 and 1989) and a three-time winner of the Tour de France (1986, 1989, and 1990), LeMond is considered by many to be the greatest American cyclist of all time, one of the great all-round cyclists of the modern era, as well as an icon of the sport's globalisation. 

LeMond retired from competition in December 1994 and was inducted into the United States Bicycling Hall of Fame in 1996. He was the first professional cyclist to sign a million-dollar contract and the first cyclist to appear on the cover of Sports Illustrated. During his career, LeMond championed several technological advancements in pro cycling, including the introduction of aerodynamic "triathlon" handlebars and carbon fiber bicycle frames.
