Lance Armstrong is a former professional cyclist from the United States, best known for winning the prestigious Tour de France seven times in a row from 1999 to 2005. His remarkable achievements made him a sports icon and a symbol of perseverance, especially after he overcame cancer. Armstrong's story inspired many, as he founded the Lance Armstrong Foundation to support cancer research and promote awareness. However, Armstrong's legacy became controversial when he was found guilty of using performance-enhancing drugs throughout his career. In 2012, he was stripped of his Tour de France titles and banned from professional cycling, leading to a significant fall from grace.
